[patch mingw]: Define _WIN32

[Kai Tietz]

Hello,

The define _WIN64 shouldn't be defined expanded.

ChangeLog

2010-08-07  Kai Tietz

        * config/i386/mingw32.h (EXTRA_OS_CPP_BUILTINS): Define _WIN64
not expanded.

I will apply this patch in a couple of hours, if there aren't any objections.

Regards,
Kai
