# Add the SDL compiler flags to the default compiler flag variables.
# It is important to do this now, before checking for headers and
# library functions. The reason being that on Windows, sdl-config
# sets the -mno-cygwin compiler option in order to generate MinGW
# executables. If we don't do this now, we might end up discovering
# header files that are not actually available to us when we come
# to compile.

# On some platforms, SDL renames main() to SDL_main() using a #define,
# so that its own main, stored in the SDLmain library, can be run first.
# Unfortunately, this causes problems for autoconf, which builds
# test programs to probe the system. All library/header/symbol checks
# must be run in this block, that performs a workaround for the problem.
