Subject: [SDL] SDL_config_macosx.h: MAC_OS_X_VERSION_MIN_REQUIRED

Hi,

I just compiled my SDL application on Mac OS X with -Wundef and it
threw a number of errors. Of note was:

     SDL_config_macosx.h: 34
     warning: "MAC_OS_X_VERSION_MIN_REQUIRED" is not defined

Line 34 is:

     #if ( (MAC_OS_X_VERSION_MIN_REQUIRED >= 1030) || (!defined (__POWERPC__)) )

Now according to this mailing on the Apple developer lists:

     http://lists.apple.com/archives/Xcode-users/2005/May/msg00602.html

that particular #define was removed from the gcc compiler defaults
and AvailabilityMacros.h (/usr/include/AvailabilityMacros.h) should
be pulled in directly instead.

Would someone closer to the Mac OS X version of SDL be willing to
make that change please? Thanks.
