I used the data member rename patch Austin and others suggested for two
days now without problems.  It lets Emacs build on Mac OS X and despite
being insufficient as a full fix, at least the users don't have to wait
for the full fix to have a working compile.

I comitted this change to the Emacs CVS HEAD, including fixing the
references to gidx in the xdisp.c docs, and will back it out (or anyone
else can back it out) if it's a problem.  I apologize in advance if
that's the case.  All the gidx references are changed to cmp_from,
that's all it does.

Thanks
