I’m trying to compile SDL-1.1.3 (or SDL-1.1.2 for that matter) using
Mingw32 from the website. But it doesn’t work. For now I’ll just go try
to get things running on BeOS. 
The problem I keep getting with both versions of SDL is:
SDL_dibaudio.h:39: parse error before HWAVEOUT' SDL_dibaudio.h:39: warning: no semicolon at end of struct or union SDL_dibaudio.h:42: parse error beforewavebuf’
