Well, that __MINGW64__ is defined unconditionally for 32-bit and
64-bit is just a rumor, which is wrong.  The macro __MINGW32__ is
defined by compiler for 32-bit and 64-bit.  The macro __MINGW64__ is
just defined for 64-bit.  At least this is the case for trunk version
of gcc.  Nevertheless those macros are not considered to check for
runtime-version, which this thread was about.

Cheers,
Kai
