Yes, thanks.

This shows the problem very clearly: for some reason, the command that
should have produced emacs.exe didn't run to completion, but rather
finished prematurely (a.k.a. crashed) after loading only a handful of
*.el files, the last one being mule-conf.el.

The Cygwin build of Emacs is currently very troubled.  In particular,
only a few versions of GCC are known to produce a working binary.
Please see the entry in etc/PROBLEMS whose header is "Building the
Cygwin port for MS-Windows can fail with some GCC version".  Also, you
will find a few discussions in the archives of this list about similar
problems that might help you find a solution.
