+# Google Android makefile for curl and libcurl
+#
+# Place the curl source (including this makefile) into external/curl/ in the
+# Android source tree.  Then build them with 'make curl' or just 'make libcurl'
+# from the Android root. Tested with Android 1.5
+#
+# Note: you must first create a curl_config.h file by running configure in the
+# Android environment. The only way I've found to do this is tricky. Perform a
+# normal Android build with libcurl in the source tree, providing the target
+# "showcommands" to make. The build will eventually fail (because curl_config.h
+# doesn't exist yet), but the compiler commands used to build curl will be
+# shown. Now, from the external/curl/ directory, run curl's normal configure
+# command with flags that match what Android itself uses. This will mean
+# putting the compiler directory into the PATH, putting the -I, -isystem and
+# -D options into CPPFLAGS, putting the -m, -f, -O and -nostdlib options into
+# CFLAGS, and putting the -Wl, -L and -l options into LIBS, along with the path
+# to the files libgcc.a, crtbegin_dynamic.o, and ccrtend_android.o. Remember
+# that the paths must be absolute since you will not be running configure from
+# the same directory as the Android make.  The normal cross-compiler options
+# must also be set.
+#
+# The end result will be a configure command that looks something like this
+# (the environment variable A is set to the Android root path):
+#
+#  A=`realpath ../..` && \
+#  PATH="$A/prebuilt/linux-x86/toolchain/arm-eabi-X/bin:$PATH" \
+#  ./configure --host=arm-linux CC=arm-eabi-gcc \
+#  CPPFLAGS="-I $A/system/core/include ..." \

+# The output .so file lacks the soname number which we currently have within the lib/Makefile.am file
+# 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).
+# Add CTests(?)
+# Check on all possible platforms
+# Test with as many configurations possible (With or without any option)
+# 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.

 This release includes the following changes:
 
- o CURLAUTH_DIGEST_IE bit added for CURLOPT_HTTPAUTH and CURLOPT_PROXYAUTH
- o VC9 Makefiles were added to the release package
+ o -T. is now for non-blocking uploading from stdin
+ o SYST handling on FTP for OS/400 FTP server cases
+ o libcurl refuses to read a single HTTP header longer than 100K
+ o added the --crlfile option to curl
 
 This release includes the following bugfixes:
 
- o build failure when disabling FTP but enabling GSS
- o fixed several calls to memory functions that didn't check return codes
- o memory leak for SSL connects with libcurl/NSS when CURLOPT_ISSUERCERT was
-   used
- o re-use of connections with the multi interface when multiple handles used
-   the same server
- o memory leak with HTTP GSS/kerberos authentication
- o removed the default use of "Pragma: no-cache"
- o fix SCP/SFTP busyloop by using a new libssh2 1.0 function
- o bad fclose() after a fatal error in cookie code
- o curl_multi_remove_handle() when the handle was in use in a HTTP pipeline
- o GSS authentication infinite loop problem
- o 550 response from SIZE no longer treated as missing file
- o ftps:// control connections now use explicit protection level
- o dotted IPv6 addresses longer than 39 bytes failed
- o curl_easy_duphandle() doesn't try to duplicate the connection cache pointer
- o build failure on OS/400 when enabling IPv6
- o better detection of SFTP failures
- o improved connection re-use for subsequent SCP and SFTP transfers
- o multi interface does less busy-loops for SCP and SFTP transfers with libssh2
-   1.0 or later
- o curl_multi_timeout() no longer returns timeout 0 when there's still more
-   than 0 but less than 999 microseconds left
- o the multi_socket API and HTTP pipelining now work a lot better when combined
- o SFTP seek/resume beyond 32bit file sizes
- o fixed breakage with --with-ssl --disable-verbose
- o TTL "leak" in the DNS cache
- o improved NSS initing
- o curl_easy_reset now resets more options
- o rare Location: follow bug with the multi interface
- o the configure script can now detect gnutls with pkg-config
- o curlbuild.h was adjusted for SunPro compilers
- o CURLOPT_COOKIELIST set to "SESS" on an easy handle with no cookies data
- o fixed timeouts for TFTP
- o fixed PPC builds
+ o The windows makefiles work again
+ o libcurl-NSS acknowledges verifyhost
+ o SIGSEGV when pipelined pipe unexpectedly breaks
+ o data corruption issue with re-connected transfers
+ o use after free if we're completed but easy_conn not NULL (pipelined)
+ o missing strdup() return code check
+ o CURLOPT_PROXY_TRANSFER_MODE could pass along wrong syntax
+ o configure --with-gnutls=PATH fixed
+ o ftp response reader bug on failed control connections
+ o improved NSS error message on failed host name verifications
+ o ftp NOBODY on re-used connection hang
+ o configure uses pkg-config for cross-compiles as well
+ o improved NSS detection in configure
+ o cookie expiry date at 1970-jan-1 00:00:00

   Changelog for the c-ares project
 
+* November 2, 2009 (Yang Tse)
+- Renamed c-ares setup.h to ares_setup.h
+
+* October 31, 2009 (Yang Tse)
+- Symbol hiding configure options are named now --enable-symbol-hiding
+  and --disable-symbol-hiding in an attempt to make them less ambiguous.
+
+* October 30, 2009 (Yang Tse)
+- Many fixes for ares_parse_txt_reply()
+
+* October 29, 2009 (Daniel Stenberg)
+- Jakub Hrozek added ares_parse_txt_reply() for TXT parsing
+
+* October 29, 2009 (Yang Tse)
+- Updated MSVC 6.0 workspace and project files that allows building
+  dynamic and static c-ares libraries in debug and release flavours.
+  Additionally each of the three sample programs is built against
+  each of the four possible c-ares libraries, generating all this
+  a total number of 12 executables and 4 libraries.
+
+* October 28, 2009 (Yang Tse)
+- Initial step towards the ability to reduce c-ares exported symbols
+  when built as a shared library based on the 'visibility' attribute
+  for GNUC and Intel compilers and based on __global for Sun compilers,
+  taking also in account __declspec function decoration for Win32 and
+  Symbian DLL's.
+
+* October 27, 2009 (Yang Tse)
+- Fixed Pelles C Win32 target compilation issues.
+
+* October 23, 2009 (Yang Tse)
+- John Engelhart noticed an unreleased problem relative to a duplicate
+  ARES_ECANCELLED error code value and missing error code description.
+
+* October 7, 2009 (Yang Tse)
+- Overhauled ares__get_hostent() Fixing out of bounds memory overwrite
+  triggered with malformed /etc/hosts file. Improving parsing of /etc/hosts
+  file. Validating requested address family. Ensuring that failures always
+  return a NULL pointer. Adjusting header inclusions.
+
+* October 6, 2009 (Yang Tse)
+- Fix ssize_t redefinition errors on WIN64 reported by Alexey Simak.
+
+* September 29, 2009 (Yang Tse)
+- Make configure script also check if _REENTRANT definition is required to
+  make errno available as a preprocessor macro.
+
+* September 7, 2009 (Yang Tse)
+- Add T_SRV portability check to ares_parse_srv_reply.c
+
+* 4 Sep 2009 (Daniel Stenberg)
+- Jakub Hrozek added ares_parse_srv_reply() for SRV parsing
+
+* 3 Aug 2009 (Daniel Stenberg)
+- Joshua Kwan fixed the init routine to fill in the defaults for stuff that
+  fails to get inited by other means. This fixes a case of when the c-ares
+  init fails when internet access is fone.
+
+- Timo Teras changed the reason code used in the resolve callback done when
+  ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to
+  better allow the callback to know what's happening.
+
+* 14 Jul 2009 (Guenter Knauf)
+- renamed generated config.h to ares_config.h to avoid any future clashes
+  with config.h from other projects.
+
+* June 20 2009 (Yang Tse)
+- Refactor how libraries are checked for connect() function in configure
+  script and check for connect() as it is done for other functions.
+
+* June 19 2009 (Yang Tse)
+- Make sclose() function-like macro definition used to close a socket,
+  now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
+  config file preprocessor definitions
+
+* June 18 2009 (Yang Tse)
+- Add CloseSocket camel case function check for configure script.
+
+* June 17 2009 (Yang Tse)
+- Check for socket() and closesocket() as it is done for other functions
+  in configure script.
+
+* June 11 2009 (Yang Tse)
+- Modified buildconf so that when automake runs it copies missing files
+  instead of symlinking them.
+
+* June 8 2009 (Yang Tse)
+- Removed buildconf.bat from release and daily snapshot archives. This
+  file is only for CVS tree checkout builds.
+
+* May 26 2009 (Yang Tse)
+- Added --enable-curldebug configure option to enable and disable building
+  with the low-level curl debug memory tracking 'feature' to allow decoupled
+  setting from --enable-debug, allowing again to build c-ares independently
+  out of the CVS tree.
+
+  For the c-ares library option --enable-debug enables debug build features
+  which are _not_ related with memory tracking. For the c-ares library when
+  --enable-debug is given it does not enable the memory tracking feature. If
+  you wish to enable the curl debug memory tracking you must use configure
+  option --enable-curldebug explicitily to do so.
+
+  Internally, definition of preprocessor symbol DEBUGBUILD restricts code
+  which is only compiled for debug enabled builds. And symbol CURLDEBUG is
+  used to differentiate code which is _only_ used for memory tracking.
+
+  Make ares_init(), ares_dup() and ares_init_options() fail returning
+  ARES_ENOTINITIALIZED if library initialization has not been performed
+  calling ares_library_init().
+
+* May 20 2009 (Yang Tse)
+- Added ares_library_init() and ares_library_cleanup() man pages.
+
+* May 19 2009 (Yang Tse)
+- Introduced ares_library_init() and ares_library_cleanup() functions.
+
+  This is an API and ABI break for Win32/64 systems. Non-Win32/64 build targets
+  using c-ares 1.6.1 can still survive without calling these functions. Read all
+  the details on ares_library_init(3) and ares_library_cleanup(3) man pages that
+  are included.
+
+  curl/libcurl 7.19.5 is fully compatible with c-ares 1.6.1 on all systems.
+
+  In order to use c-ares 1.6.1 with curl/libcurl on Win32/64 systems it is
+  required that curl/libcurl is 7.19.5 or newer. In other words, it is not
+  possible on Win32/64 to use c-ares 1.6.1 with a curl/libcurl version less
+  than 7.19.5
+
+* 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 7 2009 (Yang Tse)
+- Fix an m4 overquoting triggering a spurious 'AS_TR_CPP' symbol definition
+  attempt in generated config.h
+
+* 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

+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 dependent 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 */

+.PP
+.B void ares_library_cleanup(void)
+.PP
+.B cc file.c -lcares
+.fi
+.SH DESCRIPTION
+.PP
+The
+.B ares_library_cleanup
+function uninitializes the c-ares library, freeing all resources
+previously aquired by \fIares_library_init(3)\fP when the library
+was initialized.
+.PP
+This function must be called when the program using c-ares will
+no longer need any c-ares function. Once the program has called
+\fIares_library_cleanup(3)\fP it shall not make any further call to any
+c-ares function.
+.PP
+This function does not cancel any pending c-ares lookups or requests
+previously done. Program  must use \fIares_cancel(3)\fP for this purpose.
+.PP
+.B This function is not thread safe.
+You have to call it once the program is about to terminate, but this call must
+be done once the program has terminated every single thread that it could have
+initiated. This is required to avoid potential race conditions in library
+deinitialization, and also due to the fact that \fIares_library_cleanup(3)\fP
+might call functions from other libraries that are thread unsafe, and could
+conflict with any other thread that is already using these other libraries.
+.PP
+Win32/64 application DLLs shall not call \fIares_library_cleanup(3)\fP from
+the DllMain function. Doing so will produce deadlocks and other problems.
+.SH AVAILABILITY
+This function was first introduced in c-ares version 1.6.1 along with the
+definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_CLEANUP\fP as an
+indication of the availability of this function.
+.PP
+Since the introduction of this function, it is absolutely mandatory to call it
+for any Win32/64 program using c-ares.
+.PP
+Non-Win32/64 systems can still use c-ares version 1.6.1 without calling
+\fIares_library_cleanup(3)\fP due to the fact that it is nearly a do-nothing
+function on non-Win32/64 platforms.

+.SH NAME
+ares_library_init \- c-ares library initialization
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_library_init(int \fIflags\fP)
+.PP
+.B cc file.c -lcares
+.fi
+.SH DESCRIPTION
+.PP
+The
+.B ares_library_init
+function performs initializations internally required by the c-ares
+library that must take place before any other function provided by
+c-ares can be used in a program.
+.PP
+This function must be called one time within the life of a program,
+before the program actually executes any other c-ares library function.
+Initializations done by this function remain effective until a
+call to \fIares_library_cleanup(3)\fP is performed.
+.PP
+Successive calls to this function do nothing, only the first call done
+when c-ares is in an uninitialized state is actually effective.
+.PP
+The
+.I flags
+parameter is a bit pattern that tells c-ares exactly which features
+should be initialized, as described below. Set the desired bits by
+ORing the values together. In normal operation you should specify
+\fIARES_LIB_INIT_ALL\fP. Don't use any other value unless you are
+familiar with it and trying to control some internal c-ares feature.
+.PP
+.B This function is not thread safe.
+You have to call it once the program has started, but this call must be done
+before the program starts any other thread. This is required to avoid
+potential race conditions in library initialization, and also due to the fact
+that \fIares_library_init(3)\fP might call functions from other libraries that
+are thread unsafe, and could conflict with any other thread that is already
+using these other libraries.
+.PP
+Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the
+DllMain function. Doing so will produce deadlocks and other problems.
+.SH FLAGS
+.TP 5
+.B ARES_LIB_INIT_ALL
+Initialize everything possible. This sets all known bits.
+.TP
+.B ARES_LIB_INIT_WIN32
+Initialize Win32/64 specific libraries.
+.TP
+.B ARES_LIB_INIT_NONE
+Initialize nothing extra. This sets no bit.
+.SH RETURN VALUE
+Upon successful completion, ares_library_init() will return 0.  Otherwise, a
+non-zero error number will be returned to indicate the error. Except for
+\fIares_strerror(3)\fP, you shall not call any other c-ares function upon
+\fIares_library_init(3)\fP failure.
+.SH AVAILABILITY
+This function was first introduced in c-ares version 1.6.1 along with the
+definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_INIT\fP as an
+indication of the availability of this function.
+.PP
+Since the introduction of this function it is absolutely mandatory to
+call it for any Win32/64 program using c-ares.

+Non-Win32/64 systems can still use c-ares version 1.6.1 without calling

+/*
+ * 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
+ * dependent 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.
