thank you and looks not bad, but these are constants are used to
differentiate between gcc 3 and gcc 4 (or other versions), not to sepereate
mingw (with gcc 3.c). and mingw with gcc 4.x

But I found

__MINGW64

and think this is the right constant to differentiate between these
two "environments".

But I'm not sure if this constant is defined _every_ time, when
compiling with gcc 4.x, indenpendent if it is for 32 bit or 64 bit.

Does anybody know that?
