[Gm2] MinGW port of GM2

[Gaius Mulley]

Hi,

I've completed the MinGW cross compiler port for gm2, although I've
not stressed the generated code - but preliminary tests are working
fine. I have a more work to be done w.r.t checking it into CVS though,
hopefully the CVS will be in place later tonight..

Here is an example:

$ /usr/local/windows/bin/i386-mingw32msvc-gm2 -g -c wincat.mod
$ file wincat.o
wincat.o: 80386 COFF executable not stripped - version 30821
$ /usr/local/windows/bin/i386-mingw32msvc-gm2 -g -I. wincat.mod
$ file a.exe
a.exe: MS Windows PE Intel 80386 console executable not relocatable
