Sam Lantinga 584f8bb2ce Fixed bug 1587 - "aclocal" fails to generate a sufficient "aclocal.m4" 
Cecil Curry 2012-08-27 16:55:12 PDT

Allow "aclocal" to find the "AC_CHECK_DEFINE" macro.

On running:

   rm aclocal.m4
   libtoolize --install --copy --force
   aclocal -I acinclude
   autoconf -I acinclude

The former three commands succeed, but "autoconf" fails with:

   configure.in:198: error: possibly undefined macro: AC_CHECK_DEFINE
         If this token and others are legitimate, please use m4_pattern_allow.
         See the Autoconf documentation.

"aclocal" fails to find AC_CHECK_DEFINE and hence add such macro to
"aclocal.m4". Here is why:

* "acinclude/ac_check_define.m4" defines AC_CHECK_DEFINE via define() rather
than AC_DEFUN().
* "aclocal" fails to find macros defined via define().

                         Simple DirectMedia Layer

                                  (SDL)

                                Version 2.0

This is the Simple DirectMedia Layer, a general API that provides low
level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
and 2D framebuffer across multiple platforms.

The current version supports Windows, Windows CE, Mac OS X, Linux, FreeBSD,
NetBSD, OpenBSD, BSD/OS, Solaris, iOS, and Android. The code contains
support for other operating systems but those are not officially supported.

SDL is written in C, but works with C++ natively, and has bindings to
several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
Go, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
Pike, Pliant, Python, Ruby, and Smalltalk.

This library is distributed under the zlib license, which can be found
in the file "COPYING".

The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation is available in HTML format in "docs/index.html", and
a documentation wiki is available online at:
	http://www.libsdl.org/cgi/docwiki.cgi

The test programs in the "test" subdirectory are in the public domain.

Frequently asked questions are answered online:
	http://www.libsdl.org/faq.php

issues, you can join the developers mailing list:
