Returning modified code to the Cygwin Community

My suggestion would be to contact the authors of those original
projects.  I have talked with the folks at about
including the ipc libraries in the base distribution but since the
work includes modified Linux kernel sources and we need a copyright
assignment, it's not likely to happen soon.  It would still be good
for that library to get the benefit of your cleanup work since a good
number of people use that stuff.

I would still like to see IPC support added to Cygwin but it will need
to be either a fresh implementation or one based on less restrictive
licensing terms.  Maybe this will happen some day but I don't think
we've heard from any volunteers yet.  :-)

And please contact Corinna for the RPC changes.

Best regards,
