nedmalloc: allow compiling with MSys2's compiler

With MSys2's GCC, `ReadWriteBarrier` is already defined, and FORCEINLINE unfortunately gets defined incorrectly. Let's work around both problems, using the MSys2-specific __MINGW64_VERSION_MAJOR constant to guard the FORCEINLINE definition so as not to affect other platforms.
