+# Add full (4 or 5 libs) SSL support
+# Add INSTALL target (EXTRA_DIST variables in Makefile.am may be moved to Makefile.inc so that CMake/CPack is aware of what's to include).

+# Check on all possible platforms

+# Create scripts that help keeping the CMake build system up to date (to reduce maintenance). According to Tetetest:
+#  - lists of headers that 'configure' checks for;
+#  - curl-specific tests (the ones that are in m4/curl-*.m4 files);
+#  - (most obvious thing:) curl version numbers.
+# Add documentation subproject
+#
+# To check:
+# (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
+# (From Daniel Stenberg) The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options.

   Changelog for the c-ares project
 
+* May 11 2009 (Daniel Stenberg)
+- Gregor Jasny made c-ares link with libtool 's -export-symbols-regex option to
+  only expose functions starting with ares_.
+
+* May 2 2009 (Yang Tse)
+- Use a build-time configured ares_socklen_t data type instead of socklen_t.
+
+* April 21 2009 (Yang Tse)
+- Moved potential inclusion of system's malloc.h and memory.h header files to
+  setup_once.h.  Inclusion of each header file is based on the definition of
+  NEED_MALLOC_H and NEED_MEMORY_H respectively.
+
+* March 11 2009 (Yang Tse)
+- Japheth Cleaver fixed acountry.c replacing u_long with unsigned long.
+
+* February 20 2009 (Yang Tse)
+- Do not halt compilation when using VS2008 to build a Windows 2000 target.
+
+* February 3 2009 (Phil Blundell)
+- If the server returns garbage or nothing at all in response to an AAAA query,
+  go on and ask for A records anyway.
+
+* January 31 2009 (Daniel Stenberg)
+- ares_gethostbyname() now accepts 'AF_UNSPEC' as a family for resolving
+  either AF_INET6 or AF_INET. It works by accepting any of the looksups in the
+  hosts file, and it resolves the AAAA field with a fallback to A.
+
+* January 14 2009 (Daniel Stenberg)
+- ares.h no longer uses the HAVE_STRUCT_IN6_ADDR define check, but instead it
+  now declares the private struct ares_in6_addr for all systems instead of
+  relying on one possibly not present in the system.
+
+* January 13 2009 (Phil Blundell)
+- ares__send_query() now varies the retry timeout pseudo-randomly to avoid
+  packet storms when several queries were started at the same time.
+
+* January 11 2009 (Daniel Stenberg)
+- Phil Blundell added the internal function ares__expand_name_for_response()
+  that is now used by the ares_parse_*_reply() functions instead of the
+  ares_expand_name() simply to easier return ARES_EBADRESP for the cases where
+  the name expansion fails as in responses that really isn't expected.
+
+Version 1.6.0 (Dec 9, 2008)
+
+* December 9 2008 (Gisle Vanem)
+
+  Fixes for Win32 targets using the Watt-32 tcp/ip stack.
+
+* Dec 4 2008 (Daniel Stenberg)
+
+  Gregor Jasny provided the patch that introduces ares_set_socket_callback(),
+  and I edited it to also get duped by ares_dup().
+
+* Dec 3 2008 (Daniel Stenberg)
+
+  API changes:
+
+  I made sure the public ares_config struct looks like before and yet it
+  supports the ROTATE option thanks to c-ares now storing the "optmask"
+  internally. Thus we should be ABI compatible with the past release(s)
+  now. My efforts mentioned below should not break backwards ABI compliance.
+
+  Here's how I suggest we proceed with the API:
+
+  ares_init() will be primary "channel creator" function.
+
+  ares_init_options() will continue to work exactly like now and before. For
+  starters, it will be the (only) way to set the existing options.
+
+  ares_save_options() will continue to work like today, but will ONLY save
+  options that you can set today (including ARES_OPT_ROTATE actually) but new
+  options that we add may not be saved with this.
+
+  Instead we introduce:
+
+  ares_dup() that instead can make a new channel and clone the config used
+  from an existing channel. It will then clone all config options, including
+  future new things we add.
+
+  ares_set_*() style functions that set (new) config options. As a start we
+  simply add these for new functionality, but over time we can also introduce
+  them for existing "struct ares_options" so that we can eventually deprecate
+  the two ares_*_options() functions.
+
+  ares_get_*() style functions for extracting info from a channel handle that
+  should be used instead of ares_save_options().
+
+* Nov 26 2008 (Yang Tse)
+- Brad Spencer provided changes to allow buildconf to work on OS X.
+
+- Gerald Combs fixed a bug in ares_parse_ptr_reply() which would cause a
+  buffer to shrink instead of expand if a reply contained 8 or more records.
+
+* Nov 25 2008 (Yang Tse)
+- In preparation for the upcomming IPv6 nameservers patch, the internal
+  ares_addr union is now changed into an internal struct which also holds
+  the address family.
+
+* Nov 19 2008 (Daniel Stenberg)
+- Brad Spencer brought the new function ares_gethostbyname_file() which simply
+  resolves a host name from the given file, using the regular hosts syntax.
+
+* Nov 1 2008 (Daniel Stenberg)
+- Carlo Contavalli added support for the glibc "rotate" option, as documented
+  in man resolv.conf:
+
+  causes round robin selection of nameservers from among those listed.  This
+  has the effect of spreading the query load among all listed servers, rather
+  than having all clients try the first listed server first every time.
+
+  You can enable it with ARES_OPT_ROTATE
+
+* Oct 21 2008 (Yang Tse)
+  Charles Hardin added handling of EINPROGRESS for UDP connects.
+
+* Oct 18 2008 (Daniel Stenberg)
+  Charles Hardin made adig support a regular numerical dotted IP address for the
+  -s option as well.
+
+* Oct 7 2008 (Yang Tse)
+- Added --enable-optimize configure option to enable and disable compiler
+  optimizations to allow decoupled setting from --enable-debug.
+
+* Oct 2 2008 (Yang Tse)
+- Added --enable-warnings configure option to enable and disable strict
+  compiler warnings to allow decoupled setting from --enable-debug.
+
+* Sep 17 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of "nameser.h" to any
+  system that lacks arpa/nameser.h or arpa/nameser_compat.h header files.
+
+* Sep 16 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_writev to any
+  system that lacks the writev function.
+
+* Sep 15 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_strcasecmp to any
+  system that lacks the strcasecmp function.
+
+- Improve configure detection of some string functions.
+
+* Sep 11 2008 (Yang Tse)
+- Code reorganization to allow internal/private use of ares_strdup to any
+  system that lacks the strdup function.
+
+Version 1.5.3 (Aug 29, 2008)
+
+* Aug 25 2008 (Yang Tse)
+- Improvement by Brad House:
+
+  This patch addresses an issue in which a response could be sent back to the
+  source port of a client from a different address than the request was made to.
+  This is one form of a DNS cache poisoning attack.
+
+  The patch simply uses recvfrom() rather than recv() and validates that the
+  address returned from recvfrom() matches the address of the server we have
+  connected to. Only necessary on UDP sockets as they are connection-less, TCP
+  is unaffected.
+
+- Fix by George Neill:
+  Fixed compilation of acountry sample application failure on some systems.
+
+* Aug 4 2008 (Daniel Stenberg)
+- Fix by Tofu Linden:
+
+  The symptom:
+  * Users (usually, but not always) on 2-Wire routers and the Comcast service
+  and a wired connection to their router would find that the second and
+  subsequent DNS lookups from fresh processes using c-ares to resolve the same
+  address would cause the process to never see a reply (it keeps polling for
+  around 1m15s before giving up).
+
+  The repro:
+  * On such a machine (and yeah, it took us a lot of QA to find the systems
+  that reproduce such a specific problem!), do 'ahost www.secondlife.com',
+  then do it again.  The first process's lookup will work, subsequent lookups
+  will time-out and fail.
+
+  The cause:
+  * init_id_key() was calling randomize_key() *before* it initialized
+  key->state, meaning that the randomness generated by randomize_key() is
+  immediately overwritten with deterministic values. (/dev/urandom was also
+  being read incorrectly in the c-ares version we were using, but this was
+  fixed in a later version.)
+  * This makes the stream of generated query-IDs from any new c-ares process
+  be an identical and predictable sequence of IDs.
+  * This makes the 2-Wire's default built-in DNS server detect these queries
+  as probable-duplicates and (erroneously) not respond at all.
+
+
+* Aug 4 2008 (Yang Tse)
+- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
+  Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62
+  version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols
+  no matter if the system is AIX or not. To keep the traditional behaviour,
+  and an uniform one across autoconf versions AC_AIX is replaced with our
+  own internal macro CARES_CHECK_AIX_ALL_SOURCE.
+
+* Aug 1 2008 (Yang Tse)
+- Configure process now checks if the preprocessor _REENTRANT symbol is already
+  defined. If it isn't currently defined a set of checks are performed to test
+  if its definition is required to make visible to the compiler a set of *_r
+  functions. Finally, if _REENTRANT is already defined or needed it takes care
+  of making adjustments necessary to ensure that it is defined equally for the
+  configure process tests and generated config file.
+
+* Jul 20 2008 (Yang Tse)
+- When recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
+  now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID,
+  RECVFROM_TYPE_ARG5_IS_VOID or RECVFROM_TYPE_ARG6_IS_VOID.
+
+* Jul 17 2008 (Yang Tse)
+- RECVFROM_TYPE_ARG2, RECVFROM_TYPE_ARG5 and RECVFROM_TYPE_ARG6 are now defined
+  to the data type pointed by its respective argument and not the pointer type.
+
+* Jul 16 2008 (Yang Tse)
+- Improved configure detection of number of arguments for getservbyport_r.
+  Detection is now based on compilation checks instead of linker ones.
+
+- Configure process now checks availability of recvfrom() socket function and
+  finds out its return type and the types of its arguments. Added definitions
+  for non-configure systems config files, and introduced macro sreadfrom which
+  will be used on udp sockets as a recvfrom() wrapper in the future.
+
+* Jul 15 2008 (Yang Tse)
+- Introduce definition of _REENTRANT symbol in setup.h to improve library
+  usability.  Previously the configure process only used the AC_SYS_LARGEFILE
+  macro for debug builds, now it is also used for non-debug ones enabling the
+  use of configure options --enable-largefile and --disable-largefile which
+  might be needed for library compatibility.  Remove checking the size of
+  curl_off_t, it is no longer needed.
+
+* Jul 3 2008 (Daniel Stenberg)
+- Phil Blundell: If you ask ares_gethostbyname() to do an AF_INET6 lookup and
+  the target host has only A records, it automatically falls back to an
+  AF_INET lookup and gives you the A results.  However, if the target host has
+  a CNAME record, this behaviour is defeated since the original query does
+  return some data even though ares_parse_aaa_reply() doesn't consider it
+  relevant. Here's a small patch to make it behave the same with and without
+  the CNAME.
+
+* Jul 2 2008 (Yang Tse)
+- Fallback to gettimeofday when monotonic clock is unavailable at run-time.
+
+* Jun 30 2008 (Daniel Stenberg)
+
+- As was pointed out to me by Andreas Schuldei, the MAXHOSTNAMELEN define is
+  not posix or anything and thus c-ares failed to build on hurd (and possibly
+  elsewhere). The define was also somewhat artificially used in the windows
+  port. Now, I instead rewrote the use of gethostbyname to enlarge the host
+  name buffer in case of need and totally avoid the use of the MAXHOSTNAMELEN
+  define. I thus also removed the defien from the namser.h file where it was
+  once added for the windows build.
+
+  I also fixed init_by_defaults() function to not leak memory in case if
+  error.
+
+* Jun 9 2008 (Yang Tse)
+
+- Make libcares.pc generated file for pkg-config include information relative
+  to the libraries needed for the static linking of c-ares.
+
+* May 30 2008 (Yang Tse)
+
+- Brad House fixed a missing header file inclusion in adig sample program.
+
+Version 1.5.2 (May 29, 2008)
+
+* May 13 2008 (Daniel Stenberg)
+
+- Introducing millisecond resolution support for the timeout option. See
+  ares_init_options()'s ARES_OPT_TIMEOUTMS.
+
+* May 9 2008 (Yang Tse)
+
+- Use monotonic time source if available, for private function ares__tvnow()
+
+* May 7 2008 (Daniel Stenberg)
+
+- Sebastian made c-ares able to return all PTR-records when doing reverse
+  lookups. It is not common practice to have multiple PTR-Records for a single
+  IP, but its perfectly legal and some sites have those.
+
+- Doug Goldstein provided a configure patch: updates autoconf 2.13 usage to
+  autoconf 2.57 usage (which is the version you have specified as the minimum
+  version). It's a minor change but it does clean up some warnings with newer
+  autoconf (specifically 2.62).
+
+* May 5 2008 (Yang Tse)
+
+- Improved parsing of resolver configuration files.
+
+* April 4 2008 (Daniel Stenberg)
+
+- Eino Tuominen improved the code when a file is used to seed the randomizer.
+
+- Alexey Simak made adig support NAPTR records
+
+- Alexey Simak fixed the VC dsp file by adding the missing source file
+  ares_expand_string.c
+
 * December 11 2007 (Gisle Vanem)

+NOTES FOR C-ARES HACKERS
+
+The following notes apply to c-ares version 1.6.1 and later.
+
+* The distributed ares_build.h file is only intended to be used on systems
+  which can not run the also distributed configure script.
+
+* The distributed ares_build.h file is generated as a copy of ares_build.h.dist
+  when the c-ares source code distribution archive file is originally created.
+
+* If you check out from CVS on a non-configure platform, you must run the
+  appropriate buildconf* script to set up ares_build.h and other local files
+  before being able of compiling the library.
+
+* On systems capable of running the configure script, the configure process
+  will overwrite the distributed ares_build.h file with one that is suitable
+  and specific to the library being configured and built, this new file is
+  generated from the ares_build.h.in template file.
+
+* If you intend to distribute an already compiled c-ares library you _MUST_
+  also distribute along with it the generated ares_build.h which has been
+  used to compile it. Otherwise the library will be of no use for the users of
+  the library that you have built. It is _your_ responsability to provide this
+  file. No one at the c-ares project can know how you have built the library.
+
+* File ares_build.h includes platform and configuration dependant info,
+  and must not be modified by anyone. Configure script generates it for you.
+
+* We cannot assume anything else but very basic compiler features being
+  present. While c-ares requires an ANSI C compiler to build, some of the
+  earlier ANSI compilers clearly can't deal with some preprocessor operators.
+
+* Newlines must remain unix-style for older compilers' sake.
+
+* Comments must be written in the old-style /* unnested C-fashion */

+- When built to support IPv6, it needs to also support PF_UNSPEC or similar,
+  so that an application can ask for any protocol and then c-ares would return

+.TH ARES_DUP 3 "2 Dec 2008"
+.SH NAME
+ares_dup \- Duplicate a resolver channel
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_dup(ares_channel *\fIchannel\fP, ares_channel \fIsource\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_dup(3)\fP function duplicates an existing communications channel
+for name service lookups.  If it returns successfully, \fBares_dup(3)\fP will
+set the variable pointed to by \fIchannel\fP to a handle used to identify the
+name service channel.  The caller should invoke \fIares_destroy(3)\fP on the
+handle when the channel is no longer needed.
+
+The \fBares_dup_options\fP function also initializes a name service channel,
+with additional options set exactly as the \fIsource\fP channel has them
+configured.
+.SH SEE ALSO
+.BR ares_destroy(3),
+.BR ares_init(3)
+.SH AVAILABILITY
+ares_dup(3) was added in c-ares 1.6.0

+Daniel Stenberg

+.TH ARES_GETHOSTBYNAME 3 "25 July 1998"
+.SH NAME
+ares_gethostbyname_file \- Lookup a name in the system's hosts file
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B void ares_gethostbyname_file(ares_channel \fIchannel\fP, const char *\fIname\fP,
+.B 	int \fIfamily\fP, struct hostent **host)
+.fi
+.SH DESCRIPTION
+The
+.B ares_gethostbyname_file
+function performs a host lookup by name against the system's hosts file (or equivalent local hostname database).  
+The
+.IR channel
+parameter is required, but no asynchronous queries are performed.  Instead, the
+lookup is done via the same mechanism used to perform 'f' lookups
+(see the
+.I lookups
+options field in \fIares_init_options(3)\fP).
+The parameter
+.I name
+gives the hostname as a NUL-terminated C string, and
+.I family
+gives the desired type of address for the resulting host entry.  
+.PP
+The return value 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 and 
+.I host
+now points to the result (and must be freed with \fIares_free_hostent(3)\fP).
+.TP 19
+.B ARES_ENOTFOUND
+The hostname
+.I name
+was not found.
+.TP 19
+.B ARES_EFILE
+There was a file I/O error while performing the lookup.
+.TP 19
+.B ARES_ENOMEM
+Memory was exhausted.
+.PP
+On successful completion of the query, the pointer pointed to by
+.I host
+points to a
+.B struct hostent
+containing the address of the host returned by the lookup.  The user must
+free the memory pointed to by
+.IR host
+when finished with it by calling \fIares_free_hostent(3)\fP.  If the lookup did
+not complete successfully, 
+.I host
+will be
+.BR NULL .
+.SH AVAILABILITY
+Added in c-ares 1.5.4

+/*
+ * NOTE 1:
+ * -------
+ *
+ * All checks done in this file are intentionally placed in a public
+ * header file which is pulled by ares.h when an application is
+ * being built using an already built c-ares library. Additionally
+ * this file is also included and used when building the library.
+ *
+ * If compilation fails on this file it is certainly sure that the
+ * problem is elsewhere. It could be a problem in the ares_build.h
+ * header file, or simply that you are using different compilation
+ * settings than those used to build the library.
+ *
+ * Nothing in this file is intended to be modified or adjusted by the
+ * c-ares library user nor by the c-ares library builder.
+ *
+ * Do not deactivate any check, these are done to make sure that the
+ * library is properly built and used.
+ *
+ * You can find further help on the c-ares development mailing list:
+ * http://cool.haxx.se/mailman/listinfo/c-ares/
+ *
+ * NOTE 2
+ * ------
+ *
+ * Some of the following compile time checks are based on the fact
+ * that the dimension of a constant array can not be a negative one.
+ * In this way if the compile time verification fails, the compilation
+ * will fail issuing an error. The error description wording is compiler
+ * dependant but it will be quite similar to one of the following:
+ *
+ *   "negative subscript or subscript is too large"
+ *   "array must have at least one element"
+ *   "-1 is an illegal array size"
+ *   "size of array is negative"
+ *
+ * If you are building an application which tries to use an already
+ * built c-ares library and you are getting this kind of errors on
+ * this file, it is a clear indication that there is a mismatch between
+ * how the library was built and how you are trying to use it for your
+ * application. Your already compiled or binary library provider is the
+ * only one who can give you the details you need to properly use it.
