[ft] [PATCH] build failure on aix with gcc

[J Raynor]

freetype2 fails to build on aix when using gcc (various versions).
I've included the error messages at the bottom of this email.  The
problem is that freetype uses the -ansi flag with gcc, and that flag
causes problems with various system headers on aix, leading to the
"undeclared" errors.

I've attached a patch that makes freetype not use -ansi with gcc on aix.
