Ok.

Indeed, the problem consists on differences in the header files. Seems
that MinGW64 is diverging from MinGW at a quick pace. Adapting Emacs to
those changes is a recipe for getting even more tangled preprocessor
code in Emacs. I'm not sure it is worth the trouble unless MinGW stalls.

The toolchain I'm using is composed of 32 bit executables that produces
32 bit executables, so no crosscompiling.

The `64' in MinGW64 is just an historical artifact, it doesn't mean that
the toolchain is restricted to 64 bit hosts.
