if you are going this direction - have a look at mingw-cross-env - every
of the needed libs for gtkradiant should be included, we are using it
for uforadiant, too. the only difference is that this build chain will
produce static binaries if you don't modify the gtk related stuff (which
might be a good idea for all those gtk deps anyway)
