build problem on cygwin

[d.j.]

I nuked my local cvs emacs dir and rechecked out anew from cvs and tried 
to rebuild and am getting the same error as Angelo got.  So it is not an 
 isolated platform bug.

I was able to successfully Last Friday [using everything from  cvs  -c 
emacs ].  (Note: don't use --with-gtk on cygwin.  It breaks the build) 
I was successfull with --with-Xaw3d)
