Agreed.

We have two options:

    1. build a debuggable cygipc and continue debugging
    2. wait for true Cygwin (server) support of System V IPC

Given the following:

    http://sources.redhat.com/ml/cygwin-apps/2001-09/msg00017.html
    http://www.cygwin.com/ml/cygwin-patches/2001-q3/msg00151.html

I'm leaning toward option #2 above.

FYI, Rob Collins is the developer that recently contributed significant
(and very well done) Cygwin pthreads support and appears to be really
cranking out the new Cygwin server (including System V IPC) functionality.
