Subject: [SDL] [PATCH] SDLMain.m: fix a bug and some warnings for Mac OS X
Here are some small fixes for the src/main/macosx/SDLMain.m source
file used by Mac OS X apps:
1. setupWorkingDirectory() called chdir() within an assert(), which
gets compiled out in non-debug builds.
2. When some of gcc's optional warnings are enabled, it complains
about some implicit casts and the use of #import in SDLMain.m.
