Sorry to make a own topic for this, as it's not a big deal, but here it goes:

I was bored and so I went ahead and tried to compile DosBox with GCC 4.3.

SDL + SDL_net compiled without problems, DosBox was smooth riding aswell except for 1 file. src/hardware/vga_tseng.cpp needs to have a
#include <cstdlib>
or else compilation fails with error "abs out of scope" (this is because in GCC 4.3 the headers have been cleaned up and now everything requires thorough including. Apart from that, i didn't run into any other problems and it workes just fine, compilation was very fast aswell 😀 (compiled on Ubuntu with self-built mingw32 + gcc 4.3)

Best regards.
