Belated thanks for your advice. 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.
