Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. But,
autoconf 2.62 version of AC_AIX defines _ALL_SOURCE along with other four
preprocessor symbols no matter if the system is AIX or not. To keep the
traditional behaviour, as well as an uniform one, across autoconf versions
AC_AIX is replaced with our own internal macro.

  with -C - sent garbage in the Content-Range: header. I fixed this problem by
  making sure libcurl always sets the size of the _entire_ upload if an app
  attemps to do resumed uploads since libcurl simply cannot know the size of
  what is currently at the server end. Test 1041 is no longer disabled.

Rebooting the Solaris system, releasing allocated memory and swap,
has allowed buildconf and configure to complete sucessfully. Further
tests on the system might allow determination of the problem origin.
Solaris AutoBuilds suceeded on August 2 and 3.

when we have been doing this since revision 1.47 of configure.ac 4 years and
5 months ago when cross-compiling a Windows target. We actually don't use any
function from the Windows GDI (Graphics Device Interface) related with drawing
or graphics-related operations.

incorrectly--the host name is treated as part of the user name and the
port number becomes the password.  This can be observed in test 279

an URL in a Location: header didn't have the scope ID removed, so an
invalid host name was used.  Second, when the scope ID was removed, it
also removed any port number that may have existed in the URL.

Factored out unslashquote. Added some 'const's in function parameters.

  parser to allow numerical IPv6-addresses to be specified with the scope
  given, as per RFC4007 - with a percent letter that itself needs to be URL
  escaped. For example, for an address of fe80::1234%1 the HTTP URL is:
  "http://[fe80::1234%251]/"

147 - PHP's bug report #43158 (http://bugs.php.net/bug.php?id=43158) identifies

  true bug in libcurl built with OpenSSL. It made curl_easy_getinfo() more or
  less always return 0 for CURLINFO_SSL_VERIFYRESULT because the function that
  would set it to something non-zero would return before the assign in almost
  all error cases. The internal variable is now set to non-zero from the start
  of the function only to get cleared later on if things work out fine.
