Subject: Compiling with Intel compiler fails
I~Rve recently bought the Intel Compiler 10 for another project and decided
to compile SDL with it as well.
I was very surprised when it failed to compile because of the function:
Error 5 error: label "endS16" was referenced but not
defined ..\..\src\audio\SDL_mixer_MMX_VC.c
