dnl

|
dnl Macro to check if autoconf's compile tests have been broken by
|
|
dnl SDL. Tries to build the simplest possible program, and if it
|
|
dnl fails, calls the given block.

dnl Macro to work around SDL redefining main. The provided block
|
|
dnl is run with main #defined to SDL_main via a compiler switch
|
|
dnl if autoconf tests are found to be broken.
