Cygwin uses a lot of mingw's infrastructure for -mno-cygwin, however, I
don't believe gcj was available when I packaged gcc and gcc-mingw.
gcc-mingw is just a minor repackaging of the offerings from mingw so a
gcj-mingw would be similar.

They've already converged for the most part. Obviously the compilers
are different since the mingw compiler understands only MS-DOS paths
and the cygwin compiler understands UNIX paths but under-the-hood they
should be close to the same thing. Getting -mno-cygwin working correctly
is tricky though. It doesn't help that people often think that they can
get around portability problems by doing something like:
gcc -mno-cygwin -I/usr/include foo.c
either.
