Vadim Zeitlin 35ae03b3b2 Move wxCHECK_MINGW32_VERSION() declaration to wx/msw/gccpriv.h.
Unfortunately we can't keep it in wx/compiler.h which is included too early,
before UNICODE macro is defined, and we can't define it before including
wx/setup.h which itself must be included after wx/compiler.h.

So move it to wx/msw/gccpriv.h which is not a great solution, as the best
would be to get rid of this gcc-specific file completely, but at least should
make everything build again and ensure that _mingw.h is included after UNICODE
definition.

Closes #15805.
