Creating a Cygwin package for my app (ProofPower) sounds like a very good idea and I will look into it. Unfortunately, the enhancements to ProofPower that needed the OpenMotif bug fix are currently stymied on Cygwin by another problem. So I won’t need to bother anybody about applying my patch in the short term.
