The way WebKit does this is the following:
#if defined(__MINGW32__) /* compiler built-in define for all mingw compilers
> */
> // general mingw code
> #include <_mingw.h> /* private MinGW header */
> #if defined(__MINGW64_VERSION_MAJOR) /* best way to check for mingw-w64
> vs mingw.org */
> /* mingw-w64/w32 specific code */
>
#else
>
/* mingw.org specific code */
>
#endif /* __MINGW64_VERSION_MAJOR */
>
#endif /* __MINGW32__ */
>
They define some macro used by special macro functions (see
JavaScriptCore/wtf/Platform.h):
> #if OS(WINDOWS)
> #if COMPILER(MINGW) && !COMPILER(MINGW64)
> /* do something mingw.org specific */
> #elif COMPILER(MSVC) || COMPILER(MINGW64)
> /* other stuff */
> #endif
> #endif
>
I hope this helps!
