Actually, I do not think that ffmpeg is at fault, and I do not think it
has anything to do with C99 either. In fact, Microsofts C/C++ compiler
does not define WIN32 at all, it defines _WIN32. A lot of software
checks for WIN32 and this works only because the Visual Studio IDE by
default adds -DWIN32 to the compiler flags.

With friendly regards,
