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.

18 It is adviced to call this function only once per frame, since each call has some processing overhead\&. This is no restriction since you can pass any number of rectangles each time\&. |

20 The rectangles are not automatically merged or checked for overlap\&. In general, the programmer can use his knowledge about his particular rectangles to merge them in an efficient way, to avoid overdraw\&. |
