bug#831: 23.0.60; error in nsfonts.m


From: Austin Frank
Subject: bug#831: 23.0.60; error in nsfonts.m
Date: Sat, 30 Aug 2008 13:32:39 -0400
User-agent: Gnus/5.110011 (No Gnus v0.11) Emacs/23.0.60 (darwin)

I'm trying to build emacs from a current CVS checkout on OSX 10.4.11
with the configure option --with-ns.

Build fails because of error in nsfonts.m.  That file references a
variable called gidx, which is not defined in the relevant structure.
The attached patch changes all instances of gidx to x, and allows emacs
to build on my system.
