Re: Failure in building Emacs 23.0.50 on Cygwin

[Angelo Graziosi <Angelo.Graziosi@roma1.infn.it>]

For the sake of completeness, using Emacs CVS 20070829 07:20 (cvs -z3
-d:pserver:anonymous@cvs.savannah.gnu.org:/sources/emacs co -P -D
"29 Aug 2007 7:20" emacs) bootstraps, while the CVS of few minutes later,
7:30, fails in bootstrapping as described.

It looks the problem is in src/term.c.


Cheers,

   Angelo.
