Comment (by mojca):

 I almost forgot about this ticket. I didn't check the patches for
 `include/SDL_config.h` yet, but the rest seems like completely reasonable
 patching.

 The patch uses
 {{{
 #!c
 #if MAC_OS_X_VERSION_MIN_REQUIRED
 }}}
 while Jeremy suggested
 {{{
 #!c
 #if __MAC_OS_X_VERSION_MAX_ALLOWED
 }}}
 I always mix up the difference between the two (the idea is mostly the
 same, just different use case) and I guess Jeremy knows better.

 Thanks a lot for the good news. It probably makes sense to test that patch
 (and perhaps look at my observations above), first on 10.6, then on 10.5,
 and submit it upstream.
