sdl-ios-xcode: test/testdyngles.c annotate

annotate test/testdyngles.c @ 3164:c5b2884c26b4

Added an ifdef so that if you #define SDL_NO_COMPAT before you include SDL.h then SDL_compat.h will never be included in your code. This is useful for making sure that your code uses only SDL 1.3 features. It is also handy for finding things that are in SDL_compat.h that belong elsewhere.
