Remove HAVE_W32API_H definition and checks

All still supported versions of MinGW/Cygwin provide w32api.h file, so there is no need to test for it. This allows to simplify the code, but also remove the definition of HAVE_W32API_H from bake- and makefiles and this, in turn, allows to get rid of extra flags in MinGW format entirely, as we don't support gcc 2.95 for which they were originally needed neither.
