If we just left out that patch we won't have a problem.

Mimicing isn't a problem as long as you didn't look into the
sources and get the idea from there.  If you just looked how
it works from examining the behaviour of the binaries, that's
ok.

There's a difference.  He didn't contribute to Cygwin beyond
May 2000 and his contributions weren't AST or U/Win related
at all.

Licensing issues are really a big *@#$ but we have to be careful.
We may not even take any code which smells GPL.  It would infect
the Cygwin Library License.  For that reason we're most happy
about completely self-written code or copies/ports of BSD licensed
source.
