Thanks Jerome.  Should have tried that...

So with the patch below, unison 2.40 now builds successfully in Cygwin with
'make OSCOMP=cygwingnuc UISTYLE=text SYSTEM=generic'.  The patch is
Cygwin-specific-- I'm not sure what's the right set of #ifdef's and so on
to make the changes apply only in Cygwin.

Gene, I'll upload a new Cygwin unison2.40 package today.  With luck it will
show up in your favorite mirror by tomorrow.

Andrew.
