Yes, and there's another issue with variables, IIRC.

It's a failure of the libtoolish linking kind, and easy to check.
Apply my patch, reverert the KPSEDLL bits, get cyg-apt

    http://lilypond.org/cygwin/cyg-apt

and install a cygwin-cross compilation suite using dpkg-cross.  Hmm
that may be hairy if you're not using Debian?  Hold on...

Without my patch (new version attached) the Cygwin compile fails like
this:
