Do you compile/link from each particular mingw's bin directory when you
test ? Or do you put each mingw's bin directory in your Windows PATH
when you test ? Because my experience is that you can't just invoke gcc
or g++ without getting compile/link errors unless the particular 'bin'
directory is in the PATH.

Whatever information you can give would be helpful.
