I don't quite know how you got that makefile to produce
precisely that output. :-)

Regardless, try starting again after removing foo.o.
My guess is that you have a version of foo.o compiled
without -mno-cygwin.

If you rebuild everything, it should compile cleanly,
although I expect it will still not act the way you
want it to. If you run it from the console you won't
see any output. Try removing the -mwindows option.

I don't think you need the -L/lib/mingw or -lmingw32
options either, although they shouldn't hurt.
