MinGW-w64 does include). So we define a separate symbol which, unlike

the predefined __MINGW64__, can be used to detect this toolchain in

both 32 and 64 bit builds.

And define __MINGW32_TOOLCHAIN__ for consistency and also because it's
|

convenient as we often want to have some workarounds only for the (old)
|
|
MinGW32 but not (newer) MinGW-w64, which still predefines __MINGW32__.
