+60 - CONNECT 407 responses that kills the connection (not very likely though)

-
-To get fixed in 7.14.0
-======================
-
-55 - Add a function to the multi interface that gets file descriptors, as an
-     alternative to the curl_multi_fdset(). This is necessary to allow apps to
-     properly avoid the FD_SETSIZE problem.
-
-56 - Make curl_easy_perform() a wrapper-function that simply creates a multi
-     handle, adds the easy handle to it, runs curl_multi_perform() until the
-     transfer is done, then detach the easy handle, destroy the multi handle
-     and return the easy handle's return code. This will thus make everything
-     internally use and assume the multi interface. The select()-loop should
-     use the new function from (55).
-
-57 - Add an interface to libcurl for getting and setting cookies from an easy
-     handle. One idea: http://curl.haxx.se/mail/lib-2004-12/0195.html the
-     older idea: http://curl.haxx.se/dev/COOKIES. We need to settle on some
-     middle ground I guess.

   Changelog for the c-ares project
 
+* November 25
+
+- Yang Tse fixed some send() / recv() compiler warnings
+
+* September 18
+
+- Added constants that will be used by ares_getaddrinfo
+
+- Made ares_getnameinfo use the reentrant getservbyport (getservbyport_r) if it is
+  available to ensure it works properly in a threaded environment.
+
+* September 10
+
+- configure fix for detecting a member in the sockaddr_in6 struct which failed
+  on ipv6-enabled HP-UX 11.00
+
+Version 1.3.0 (August 29, 2004)
+
+* August 21
+
+- Alfredo Tupone provided a fix for the Windows code in get_iphlpapi_dns_info()
+  when getting the DNS server etc.
+
+* June 19
+
+- Added some checks for the addrinfo structure.
+
+* June 2
+
+- William Ahern:
+
+  Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a
+  read event can come back from poll() on a valid SOCK_DGRAM socket but
+  recv(2) will still block. This patch doesn't ignore EAGAIN in
+  read_udp_packets(), though maybe it should. (This patch was edited by Daniel
+  Stenberg and a new configure test was added (imported from curl's configure)
+  to properly detect what non-blocking socket approach to use.)
+
+  I'm not quite sure how this was happening, but I've been seeing PTR queries
+  which seem to return empty responses. At least, they were empty when calling
+  ares_expand_name() on the record. Here's a patch which guarantees to
+  NUL-terminate the expanded name. The old behavior failed to NUL-terminate if
+  len was 0, and this was causing strlen() to run past the end of the buffer
+  after calling ares_expand_name() and getting ARES_SUCCESS as the return
+  value. If q is not greater than *s then it's equal and *s is always
+  allocated with at least one byte.
+
+* May 16
+
+- Added ares_getnameinfo which mimics the getnameinfo API (another feature
+  that could use testing).
+
+* May 14
+
+- Added an inet_ntop function from BIND for systems that do not have it.
+
+* April 9
+
+- Made sortlist support IPv6 (this can probably use some testing).
+
+- Made sortlist support CIDR matching for IPv4.
+
+* April 8
+
+- Added preliminary IPv6 support to ares_gethostbyname. Currently, sortlist
+  does not work with IPv6. Also provided an implementation of bitncmp from
+  BIND for systems that do not supply this function. This will be used to add
+  IPv6 support to sortlist.
+
+- Made ares_gethostbyaddr support IPv6 by specifying AF_INET6 as the family.
+  The function can lookup IPv6 addresses both from files (/etc/hosts) and
+  DNS lookups.
+
+* April 7
+
+- Tupone Alfredo fixed includes of arpa/nameser_compat.h to build fine on Mac
+  OS X.
+
+* April 5
+
+- Dominick Meglio: Provided implementations of inet_net_pton and inet_pton
+  from BIND for systems that do not include these functions.
+
+* March 11, 2005
+
+- Dominick Meglio added ares_parse_aaaa_reply.c and did various
+  adjustments. The first little steps towards IPv6 support!
+
 * November 7
 
 - Fixed the VC project and makefile to use ares_cancel and ares_version

+.SH NAME
+ares_getnameinfo \- Address-to-nodename translation in protocol-independent manner
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B typedef void (*ares_nameinfo_callback)(void *\fIarg\fP, int \fIstatus\fP,
+.B	char *\fInode\fP, char *\fIservice\fP)
+.PP
+.B void ares_getnameinfo(ares_channel \fIchannel\fP, const struct sockaddr *\fIsa\fP,
+.B 	socklen_t \fIsalen\fP, int \fIflags\fP, ares_nameinfo_callback \fIcallback\fP,
+.B 	void *\fIarg\fP)
+.fi
+.SH DESCRIPTION
+The
+.B ares_getnameinfo
+function is defined for protocol-independent address translation. The function
+is a combination of \fIares_gethostbyaddr(3)\fP and \fIgetservbyport(3)\fP. The function will
+translate the address either by executing a host query on the name service channel
+identified by
+.IR channel 
+or it will attempt to resolve it locally if possible.
+The parameters
+.I sa
+and
+.I len
+give the address as a sockaddr structure, and
+.I flags
+gives the options that the function will use.  Valid flags are listed below:
+.TP 19
+.B ARES_NI_NOFQDN
+Only the nodename portion of the FQDN is returned for local hosts.
+.TP 19
+.B ARES_NI_NUMERICHOST
+The numeric form of the hostname is returned rather than the name.
+.TP 19
+.B ARES_NI_NAMEREQD
+An error is returned if the hostname cannot be found in the DNS.
+.TP 19
+.B ARES_NI_NUMERICSERV
+The numeric form of the service is returned rather than the name.
+.TP 19
+.B ARES_NI_TCP
+The service name is to be looked up for the TCP protocol.
+.TP 19
+.B ARES_NI_UDP
+The service name is to be looked up for the UDP protocol.
+.TP 19
+.B ARES_NI_SCTP
+The service name is to be looked up for the SCTP protocol.
+.TP 19
+.B ARES_NI_DCCP
+The service name is to be looked up for the DCCP protocol.
+.TP 19
+.B ARES_NI_NUMERICSCOPE
+The numeric form of the scope ID is returned rather than the name.
+.TP 19
+.B ARES_NI_LOOKUPHOST
+A hostname lookup is being requested.
+.TP 19
+.B ARES_NI_LOOKUPSERVICE
+A service name lookup is being requested.
+.PP
+When the query
+is complete or has 
+failed, the ares library will invoke \fIcallback\fP.  Completion or failure of 
+the query may happen immediately, or may happen during a later call to
+\fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP.
+.PP
+The callback argument
+.I arg
+is copied from the
+.B ares_getnameinfo
+argument
+.IR arg .
+The callback argument
+.I status
+indicates whether the query succeeded and, if not, how it failed.  It
+may have any of the following values:
+.TP 19
+.B ARES_SUCCESS
+The host lookup completed successfully.
+.TP 19
+.B ARES_ENOTIMP
+The ares library does not know how to look up addresses of type
+.IR family .
+.TP 19
+.B ARES_ENOTFOUND
+The address
+.I addr
+was not found.
+.TP 19
+.B ARES_ENOMEM
+Memory was exhausted.
+.TP 19
+.B ARES_EDESTRUCTION
+The name service channel
+.I channel
+is being destroyed; the query will not be completed.
+.TP 19
+.B ARES_EBADFLAGS
+The
+.I flags
+parameter contains an illegal value.
+.PP
+On successful completion of the query, the callback argument
+.I node
+contains a string representing the hostname (assuming 
+.B ARES_NI_LOOKUPHOST
+was specified). Additionally, 
+.I service
+contains a string representing the service name (assuming
+.B ARES_NI_LOOKUPSERVICE
+was specified).
+If the query did not complete successfully, or one of the values
+was not requested, 
+.I node
+or
+.I service
+will be 
+.BR NULL .

+.SH NAME
+ares_parse_aaaa_reply \- Parse a reply to a DNS query of type AAAA into a hostent
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_parse_aaaa_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
+.B 	struct hostent **\fIhost\fP);
+.fi
+.SH DESCRIPTION
+The
+.B ares_parse_aaaa_reply
+function parses the response to a query of type AAAA into a
+.BR "struct hostent" .
+The parameters
+.I abuf
+and
+.I alen
+give the contents of the response.  The result is stored in allocated
+memory and a pointer to it stored into the variable pointed to by
+.IR host .
+It is the caller's responsibility to free the resulting host structure
+using
+.BR ares_free_hostent (3)
+when it is no longer needed.
+.SH RETURN VALUES
+.B ares_parse_aaaa_reply
+can return any of the following values:
+.TP 15
+.B ARES_SUCCESS
+The response was successfully parsed.
+.TP 15
+.B ARES_EBADRESP
+The response was malformatted.
+.TP 15
+.B ARES_ENODATA
+The response did not contain an answer to the query.
+.TP 15
+.B ARES_ENOMEM
+Memory was exhausted.
+.SH SEE ALSO
+.BR ares_gethostbyname (3),
+.BR ares_free_hostent (3)

+
+Condition
+
+ This document is written to describe the situation as it is right
+ now. libcurl 7.15.0 is currently the latest version available. Things may (or
+ perhaps will) of course change in the future.
+
+ This document reflects my view and understanding of these things. Please tell
+ me where and how you think I'm wrong, and I'll try to correct my mistakes.
+
+Background 
+
+ The Free Software Foundation has deemed the Original BSD license[1] to be
+ "incompatible"[2] with GPL[3]. I'd rather say it is the other way around, but
+ the point is the same: if you distribute a binary version of a GPL program,
+ it MUST NOT be linked with any Original BSD-licensed parts or
+ libraries. Doing so will violate the GPL license. For a long time, very many
+ GPL licensed programs have avoided this license mess by adding an
+ exception[8] to their license. And many others have just closed their eyes
+ for this problem.
+
+ libcurl is MIT-style[4] licensed - how on earth did this dilemma fall onto
+ our plates?
+
+ libcurl is only a little library. libcurl can be built to use OpenSSL for its
+ SSL/TLS capabilities. OpenSSL is basically Original BSD licensed[5].
+
+ If libcurl built to use OpenSSL is used by a GPL-licensed application and you
+ decide to distribute a binary version of it (Linux distros - for example -
+ tend to), you have a clash. GPL vs Original BSD.
+
+ This dilemma is not libcurl-specific nor is it specific to any particular
+ Linux distro. (This article mentions and refers to Debian several times, but
+ only because Debian seems to be the only Linux distro to have faced this
+ issue yet since no other distro is shipping libcurl built with two SSL
+ libraries.)
+
+Part of the Operating System
+
+ This would not be a problem if the used lib would be considered part of the
+ underlying operating system, as then the GPL license has an exception
+ clause[6] that allows applications to use such libs without having to be
+ allowed to distribute it or its sources. Possibly some distros will claim
+ that OpenSSL is part of their operating system.
+
+ Debian does however not take this stance and has officially(?) claimed that
+ OpenSSL is not a required part of the Debian operating system
+
+Debian-legal
+
+ In August 2004 I figured I should start pulling people's attention to this to
+ see if anyone has any bright ideas or if they would dismiss my worries based
+ on some elegant writing I had missed somewhere:
+
+ My post to debian-legal on August 12 2004:
+
+        http://lists.debian.org/debian-legal/2004/08/msg00279.html
+
+ Several people agreed then that this is a known and rather big problem, but
+ the following discussion didn't result in much.
+
+GnuTLS
+
+ With the release of libcurl 7.14.0 (May 2005), it can now get built to use
+ GnuTLS instead of OpenSSL. GnuTLS is a LGPL[7] licensed library that offers a
+ matching set of features as OpenSSL does. Now, you can build and distribute
+ an SSL capable libcurl without including any Original BSD licensed code.
+
+ I believe Debian is the first distro to provide libcurl/GnutTLS packages.
+
+GnuTLS vs OpenSSL
+
+ While these two libraries offer similar features, they are not equal. Both
+ libraries have features the other one lacks. libcurl does not (yet) offer a
+ standardized stable ABI if you decide to switch from using libcurl-openssl to
+ libcurl-gnutls or vice versa. The GnuTLS support is very recent in libcurl
+ and it has not been tested nor used very extensively, while the OpenSSL
+ equivalent code has been used and thus matured for more than seven (7) years.
+
+ In August 2005, the debian-devel mailing list discovered the license issue as
+ a GPL licensed application wanted SSL capabilities from libcurl and thus was
+ forced to use the GnuTLS powered libcurl. For a reason that is unknown to me,
+ the application authors didn't want to or was unable to add an exception to
+ their GPL license. Alas, the license problem hit the fan again.
+
+ GnuTLS
+   - LGPL licensened
+   - supports SRP
+   - lacks SSLv2 support
+   - lacks MD2 support (used by at least some CA certs)
+
+ OpenSSL
+   - Original BSD licensened
+   - lacks SRP
+   - supports SSLv2
+   - older and more widely used
+
+The Better License, Original BSD or LGPL?
+
+ It isn't obvious or without debate to any objective interested party that
+ either of these licenses are the "better" or even the "preferred" one in a
+ generic situation.
+
+ Instead, I think we should accept the fact that the SSL/TLS libraries and
+ their different licenses will fit different applications and their authors
+ differently depending on the applications' licenses and their general usage
+ pattern (considering how LGPL libraries for example can be burdensome for
+ embedded systems usage).
+
+ In Debian land, there seems to be a common opinion that LGPL is "maximally
+ compatible" with apps while Original BSD is not. Like this:
+
+        http://lists.debian.org/debian-devel/2005/09/msg01417.html
+
+More SSL Libraries
+
+ In libcurl, there's no stopping us here. There are at least a few more Open
+ Source/Free SSL/TLS libraries and we would very much like to support them as
+ well, to offer application authors an even wider scope of choice.
+
+Application Angle of this Problem
+
+ libcurl is built to use one SSL/TLS library. It uses a single fixed name (by
+ default), and applications are built/linked to use that single lib. Replacing
+ one libcurl instance with another one that uses the other SSL/TLS library
+ might break one or more applications (due to ABI differences and/or different
+ feature set). You want your application to use the libcurl it was built for.
+
+Project cURL Angle of this Problem
+
+ We distribute libcurl and everyone may build libcurl with either library. At
+ their choice. This problem is not directly a problem of ours. It merely
+ affects users - GPL application authors only - of our lib as it comes
+ included and delivered on some distros.
+
+ libcurl has different ABI when built with different SSL/TLS libraries due to
+ two reasons:
+
+ 1. No one has worked on fixing this. The mutex/lock callbacks should be set
+    with a generic libcurl function that should use the proper underlying
+    functions.
+
+ 2. The CURLOPT_SSL_CTX_FUNCTION option is not possible to "emulate" on GnuTLS
+    but simply requires OpenSSL.
+
+Distro Angle of this Problem
+
+ A distro can provide separate libcurls built with different SSL/TLS libraries
+ to work around this, but at least Debian seems to be very hostile against
+ such an approach, probably since it makes things like devel packages for the
+ different libs collide since they would provide the same include files and
+ man pages etc.
+
+Fixing the Only Problem
+
+ The only problem is thus for distributions that want to offer libcurl
+ versions built with more than one SSL/TLS library.
+
+ Debian is now (since mid September 2005) providing two different devel
+ packages, one for libcurl built with OpenSSL and one built with GnuTLS. They
+ use different .so names and can this both be installed in a single system
+ simultaneously. This has previously been said as a transitional system not
+ desired to keep in the long run.
+
+ Since multiple libcurl binaries using different names are ruled out, we need
+ to come up with a way to have one single libcurl that someone uses different
+ underlying libraries. The best(?) approach currently suggested involves this:
+
+ A new intermediate library (named lib2 so far in the discussions) with the
+ single purpose of providing libcurl with SSL/TLS capabilities. It would have
+ a unified API and ABI no matter what underlying library it would use.
+
+ There would be one lib2 binary provided for each supported SSL/TLS library.
+ For example: lib2-openssl, lib2-gnutls, lib2-yassl, lib2-matrixssl and
+ lib2-nossl. Yes, take note of the last one that provides the lib2 ABI but
+ that lacks the actual powers.
+
+ When libcurl is built and linked, it will be linked against a lib2 with the
+ set ABI.
+
+ When you link an app against libcurl, it would also need to provide one of
+ the (many) lib2 libs to decide what approach that fits the app. An app that
+ doesn't want SSL at all would still need to link with the lib2-nossl lib.
+
+ GPL apps can pick the lib2-gnutls, others may pick the lib2-openssl.
+
+ This concept works equally well both for shared and static libraries.
+
+ A positive side effect of this approach could be a more generic "de facto"
+ standard API for SSL/TLS libraries.
+
+When Will This Happen
+
+ Note again that this is not a problem in curl, it doesn't solve any actual
+ technical problems in our project. Don't hold your breath for this to happen
+ very soon (if at all) unless you step forward and contribute.
+
+ The suggestion that is outlined above is still only a suggestion. Feel free
+ to bring a better idea!
+
+ Also, to keep in mind: I don't want this new concept to have too much of an
+ impact on the existing code. Preferably it should be possible to build the
+ code like today (without the use of lib2), should you decide to ignore the
+ problems outlined in this document.

+   If you want to compile with zlib support, you will need to build

+   If you want to compile with SSL support you need the OpenSSL package.

+   the OpenSSL libraries.  The build process of OpenSSL generates the
+   libeay32.dll and ssleay32.dll files in the out32dll subdirectory in
+   the OpenSSL home directory.  OpenSSL static libraries (libeay32.lib,
+   ssleay32.lib, RSAglue.lib) are created in the out32 subdirectory.
+
+   Before running nmake define the OPENSSL_PATH environment variable with
+   the root/base directory of OpenSSL, for example:
+
+     set OPENSSL_PATH=c:\openssl-0.9.7d
+
+   Then run 'nmake vc-ssl' or 'nmake vc-ssl-dll' in curl's root
+   directory.  'nmake vc-ssl' will create a libcurl static and dynamic
+   libraries in the lib subdirectory, as well as a statically linked
+   version of curl.exe in the src subdirectory.  This statically linked
+   version is a standalone executable not requiring any DLL at
+   runtime. This make method requires that you have the static OpenSSL
+   libraries available in OpenSSL's out32 subdirectory.
+   'nmake vc-ssl-dll' creates the libcurl dynamic library and
+   links curl.exe against libcurl and OpenSSL dynamically.
+   This executable requires libcurl.dll and the OpenSSL DLLs
+   at runtime.
+   Run 'nmake vc-ssl-zlib' to build with both ssl and zlib support.

-        you may find it in 'C:\Program Files\Microsoft Visual Studio\vc98\bin'
-        provided that you installed Visual C/C++ 6 in the default directory.
-
-        Then run 'nmake vc' in curl's root directory.
-
-        If you want to compile with zlib support, you will need to build
-        zlib (http://www.gzip.org/zlib/) as well. Please read the zlib
-        documentation on how to compile zlib. Define the ZLIB_PATH environment
-        variable to the location of zlib.h and zlib.lib, for example:
-
-          set ZLIB_PATH=c:\zlib-1.2.1
-
-        Then run 'nmake vc-zlib' in curl's root directory.
-
-        If you want to compile with SSL support you need the OpenSSL package.
-        Please read the OpenSSL documentation on how to compile and install
-        the OpenSSL libraries.  The build process of OpenSSL generates the
-        libeay32.dll and ssleay32.dll files in the out32dll subdirectory in
-        the OpenSSL home directory.  OpenSSL static libraries (libeay32.lib,
-        ssleay32.lib, RSAglue.lib) are created in the out32 subdirectory.
-
-        Before running nmake define the OPENSSL_PATH environment variable with
-        the root/base directory of OpenSSL, for example:
-
-          set OPENSSL_PATH=c:\openssl-0.9.7d
-
-        Then run 'nmake vc-ssl' or 'nmake vc-ssl-dll' in curl's root
-        directory.  'nmake vc-ssl' will create a libcurl static and dynamic
-        libraries in the lib subdirectory, as well as a statically linked
-        version of curl.exe in the src subdirectory.  This statically linked
-        version is a standalone executable not requiring any DLL at
-        runtime. This make method requires that you have the static OpenSSL
-        libraries available in OpenSSL's out32 subdirectory.
-        'nmake vc-ssl-dll' creates the libcurl dynamic library and
-        links curl.exe against libcurl and OpenSSL dynamically.
-        This executable requires libcurl.dll and the OpenSSL DLLs
-        at runtime.
-        Run 'nmake vc-ssl-zlib' to build with both ssl and zlib support.
-
-      Microsoft / Borland style
-      -------------------------
-        If you have OpenSSL, and want curl to take advantage of it, edit your
-        project properties to use the SSL include path, link with the SSL libs
-        and define the USE_SSLEAY symbol.

+==================================
+
+Reference Emails available at curl@haxx.se: 
+
+  Libcurl Install and Use Issues
+  Awaiting an Answer for Win 32 Install 
+  res = curl_easy_perform(curl); Error
+  Makefile Issues
+  
+
+Having previously done a thorough review of what was available that met my
+requirements under GPL, I settled for Libcurl as the software of choice for
+many reasons not the least of which was the support.
+
+Background
+----------
+
+This quest started when I innocently tried to incorporate the libcurl library
+into my simple source code. I figured that a few easy steps would accomplish
+this without major headaches. I had no idea that I would be facing an almost
+insurmountable challenge.
+
+The main problem lies in two areas. First the bulk of support for libcurl
+exists for a Unix/linux command line environments. This is of little help when
+it comes to Windows O/S.
+
+Secondly the help that does exist for the Windows O/S focused around mingw
+thru a command line argument environment.
+
+You may ask "Why is this a problem?"
+
+I'm using a Windows O/S with DevCpp. For those of you who are unfamiliar with
+DevCpp, it is a window shell GUI that replaces the command line environment
+for gcc. A definite improvement that I am unwilling to give up. However using
+DevCpp presented its own set of issues. Inadvertently I also made some
+careless errors such as compiling the 7.14 version of Makefile with an older
+version of source code. Thanks to Dan Fandrich for picking this up.
+
+I did eventually with the help of Daniel, Phillipe and others manage to
+implement successfully (the only mingw available version)
+curl-7.13.0-win32-ssl-devel-mingw32 into the DevCpp environment. Only the
+dynamic libcurl.dll libcurldll.a libraries worked. The static library which I
+was interested in did not. Furthermore when I tried to implement one of the
+examples included with the curl package (get info.c) it caused the executable
+to crash. Tracing the bug I found it in the code and function res =
+curl_easy_perform(curl);.
+
+At this point I had to make a choice as to whether invest my limited
+time-energy resource to fixing the bug or to compile the new version
+available. After searching the archives I found a very similar or the same bug
+reported from version 7.12x on. Daniel did inform me that he thought that this
+bug had been fixed with the latest version. So I proceeded to compile the
+latest SSL version where I faced other challenges.
+
+In order to make this process unremarkable for others using the same
+environment I decided to document the process so that others will find it
+routine. It would be a shame if newbies could not implement this excellent
+package for their use.
+
+I would like to thank the many others in this forum and in the DevCpp forum
+for their help. Without your help I may either have given up or it would have
+taken me many times longer to achieve success.
+
+The Cookbook Approach
+---------------------
+
+This discussion will be confined to a SSL static library compilation and
+installation. Limited mention and comments will be inserted where appropriate
+to help with non-SSL, dynamic libraries and executables.
+
+
+   Using Makefile from DevCpp to compile Libcurl libraries
+
+Preamble
+--------
+
+Using the latest version release - curl-7.14.0.tar.gz. Curl source code is
+platform independent. This simply means that the source code can be compiled
+for any Operating System (Linux/Unix Windows etc. and variations of thereof).
+
+The first thing to note is that inside curl-7.14.0 you will find two folders
+lib and src. Both contain Makefile.m32 (required for win mingw library or exe
+compilation) files which are different. The main difference between these two
+folders and the makefiles is that the src folder contents are used to compile
+an executable file(curl.exe) while the lib folder contents are used to compile
+a static (libcurl.a) and dynamic (libcurl.dll & libcurldll.a) file that can be
+used to compile libcurl with your own source code so that one can use and
+access all libcurl functions.
+
+Before we start please make sure that DevCpp is installed properly. In
+particular make sure you have no spaces in the name of any of the directories
+and subdirectories where DevCpp is installed. Failure to comply with the
+install instructions may produce erratic behaviour in DevCpp. For further info
+check the following sites
+
+http://aditsu.freeunixhost.com/dev-cpp-faq.html
+http://sourceforge.net/forum/message.php?msg_id=3252213
+
+As I have mentioned before I will confine this to the SSL Library compilations
+but the process is very similar for compilation of the executable - curl.exe;
+just substitute the src folder makefile in its stead.
+
+First use a text processor Notepad, or your own favourite text processor. To
+engage your favourite text processor, select Makefile.m32 click once with your
+mouse on file icon; icon turns blue, press the shift key and right-click on
+mouse, menu appears select "Open with", select your favourite text processor.
+
+Next read the contents of Makefile.m32. It includes instructions on its use.
+
+Method I - DOS Command Line
+---------------------------
+ 
+Note - The only reason I have included this method is that Method II which is
+the preferred method for compiling does not allow for the setting of option
+switches (e.g. SSL = 1 or SSL =0). At least that's what they tell me at the
+Dev-Cpp forum.
+
+1 - Make a copy of (D:\Dev-Cpp\bin) bin folder and name it "bin Original"
+place it in the Dev-Cpp installed directory (D:\Dev-Cpp\ for this example)
+
+2 - Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into the bin folder above (D:\Dev-Cpp\bin). The reason being is that
+the make.exe file resides in this folder. Make.exe will use - Makefile.m32,
+Makefile.inc, and the source code included in the lib folder to compile the
+source code. There is a PATH issue with make.exe that remains unresolved at
+least for me. Unless the entire source code to be compiled is placed entirely
+within the directory of make.exe an error message will be generated - "file
+xxxx.yyy not available".
+
+3- Go to Dev-Cpp\bin and double click on make .exe. You will see a DOS window
+quickly pop up and close very quickly. Not to worry! Please do not skip this
+step.
+
+4- Click on the start button\Programs\MS-DOS Prompt.Once the DOS Window is up
+Type the disk drive letter (e.g. E: ) engage the enter button. The path should
+automatically take you to the directory of the make.exe file.
+
+5- To compile the source code simply type at the DOS prompt make -f
+Makefile.m32 as per instructions contained in the Makefile.m32 file (use any
+text processor to read instructions). I don't believe that this makefile
+allows for the option of non SSL. Ignore any warnings.
+
+6- Collect and make copies of libcurl.a, libcurl.dll, libcurldll.a and any *.o
+compilations you might need in another directory outside of the bin directory
+as you will need this files shortly to set up libcurl for use with
+Dev-cpp. For most apps *.o is not required. Later on we will show what to do
+with these files.
+
+7- You are finished but before closing we need to do cleanup - erase the bin
+folder and rename the "bin Original" folder created in step 1 to bin.
+
+Note to compile a curl executable the process is probably similar but instead
+of using the LIB folder contents use the SRC folder contents and Makefiles in
+curl-7.14.0.tar.gz. File directories relative placements must be respected for
+compiling to take place successfully. This may not be possible with the PATH
+problem that make.exe experiences. If anyone has solved this PATH issue and
+please make sure it actually works on Win 9x/2000/XP before letting me
+know. Then please let me or Daniel in on the solution so that it can be
+included with these instructions. Thanks.
+
+or
+
+Method II - Dev-Cpp GUI
+-----------------------
+
+1- Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into any folder outside of (Dev-Cpp\bin).
+
+2- Drop the File/New/click on Project.
+
+3- New Project Dialogue box appears. Double click on the Static Library.
+
+4- Create Project Dialogue box appears. Select the LIB folder location to
+place and locate your Project File Name. Placing the Project File Name
+elsewhere may cause problems (PATH issue problem again).
+
+5- Drop down the Project/Project Options. Project Options Dialogue box
+appears.
+
+6- Select the Makefile tab in the Project Options Dialogue Box. Check Box -
+Use Custom Makefile. Click on the Folder icon at the extreme right of the
+Check Box. Select Makefile.m32 in the folder wherever you have placed the
+contents of the LIB Folder. Press OK and close the Dialogue Box.
+
+7- Drop the Menu Project/Click on Add to Project. Open File Dialogue Box
+appears.  The Dialogue Box should open in the folder wherever you have placed
+the contents of the LIB Folder. If not go there.
+
+8- Select Crtl-A to select all files in the LIB folder. Click on open to add
+files and close box. Wait till all files are added. This may take 30 seconds
+or longer.
+
+9- Drop the Menu Execute/Click on Compile. 
+
+10- That's it.
+
+
+   The following steps must be completed if Curl is to work properly
+   =================================================================
+
+LIB folder inclusions (*.a placement)
+-------------------------------------
+
+1- Refer to Method I - DOS Command Line point # 6 Take libcurl.a, libcurldll.a
+and install it in the directory C( or whichever drive Dev is installed)
+:\Dev-Cpp\lib.
+
+
+Include Folder
+--------------
+
+1- Create a new folder by the name of curl (do not change the name curl to
+some other name as it will cause major issues) in the directory
+C:\Dev-Cpp\include.
+
+2- Copy the entire contents of the curl folder of curl-7.14.0.tar.gz or zip
+ version into the newly created curl directory - C:\Dev-Cpp\include\curl.
+
+Links To Include And Lib Folder
+-------------------------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Libraries. Make sure
+that C( or whichever drive Dev is installed):\DEV-CPP\lib is included.
+
+2- Next select the Menu - Tools\Compiler Options\Directories\C Includes. Make
+sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are included.
+
+3- Next select the Menu - Tools\Compiler Options\Directories\C++
+Includes. Make sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are
+included.
+
+Linker Links
+------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Compiler.
+
+2- Make sure that the box "Add these commands to the linker command line" is
+checked.
+
+3- Include in the white space immediately below the box referred in 2 -lcurl
+-lws2_32 -lwinmm.
+
+SSL Files
+---------
+
+1- Get the latest openSSL (as of time of this writing)
+openssl-0.9.7e-win32-bin.zip for the minimalist package of the openssl-0.9.7e
+binaries ported to MS Windows 95/98/NT/XP using the MingW32/GCC-3.1
+development environment. The file may be downloaded at
+http://curl.haxx.se/download/.
+
+2- Open the above zip file. You will find two files - SDL.dll,
+SDL_mixer.dll. Install them in the directory C:\WINDOWS\SYSTEM32 for Win 9x
+users and c:\winnt\system32 for NT-family users.
+
+Multithreading Files
+--------------------
+
+To be completed
+
+#define
+-------
+
+1- Make sure that your program includes the following - #define CURL_STATICLIB
+must be declared FIRST before any other define functions may be
+added. Otherwise you may experience link errors.
+
+2- Don't forget to include   #include "curl/curl.h".
+
+e.g.
+    #define CURL_STATICLIB 
+#include <windows.h>
+    #include "curl/curl.h"
+#include <fstream>
+#include <iostream>
+#include <vector>
+etc...
+
+
+Static or Dynamic Library
+-------------------------
+
+The above steps apply for the use by a static library. Should you choose to
+use a dynamic library you will be required to perform these additional steps.
+
+1- Refer to Method I - DOS Command Line point # 6. Install libcurl.dll in the
+directory C:\WINDOWS\SYSTEM32 for Win 9x users and c:\winnt\system32 for
+NT-family users.
+
+2- Refer to Linker Links point 3 - Replace -lcurl with -lcurldll.
+
+Voila you're done.
+
+The non-SSL static Library build may not be possible to use at least as of the
+time of this writing - v7.14. Check reference emails - Phillipe and I found it
+impossible to fully compile as certain files were missing for linking. No big
+loss as SSL is a major plus.
+
+Hope this Helps

+22. Sending files to a FTP server using curl on VMS, might lead to curl
+  complaining on "unaligned file size" on completion. The problem is related

+doesn't.  The default is nonzero, but before 7.10, it was zero.
+
+When negotiating an SSL connection, the server sends a certificate
+indicating its identity.  Curl verifies whether the certificate is
+authentic, i.e. that you can trust that the server is who the
+certificate says it is.  This trust is based on a chain of digital
+signatures, rooted in certification authority (CA) certificates you
+supply.  As of 7.10, curl installs a default bundle of CA certificates
+and you can specify alternate certificates with the
+\fICURLOPT_CAINFO\fP option or the \fICURLOPT_CAPATH\fP option.
+
+When \fICURLOPT_SSL_VERIFYPEER\fP is nonzero, and the verification
+fails to prove that the certificate is authentic, the connection
+fails.  When the option is zero, the connection succeeds regardless.
+
+Authenticating the certificate is not by itself very useful.  You
