You're compiling _under_ wine, and since wine attempts to be windows,
gcc will think you're on windows. If you want to compile a winelib
program/dll (i.e. a dll built specifically for wine and not windows)
you use winegcc which defines __WINE__. winegcc -E -dM foo.c should
contain #define __WINE__ 1.
