I once wrote code that did that for the DJGPP port.  If someone is
interested, I can tell where to find that (it's part of the DJGPP
debug support library).  It didn't support all the redirection
features of the Posix shell, but that shouldn't be too hard to add, I
think.  Some of the code there (the juggling with standard handles
when control jumps between GDB and the inferior) is not needed for
Cygwin, I think.
