Re: Currnet CVS fails to configure

[Greg Troxel <gdt@fnord.ir.bbn.com>]

I am pretty sure I had this problem too, and commented it out.
I think the problem may be that the gtk.m4 that comes with gtk 1.2
defines only AM_PATH_GTK, and not AM_PATH_GTK_2_0.  So we either need
to avoid using it, to avoid using it (so that configure runs) if 2.0
is not installed, or to include the .m4 source in acinclude.m4.
But aclocal may choke if it is multiply defined.
I think the hard lesson here is that automake/aclocal is not forgiving
of interface changes in programs' .m4 files.

Of course, one can require having up-to-date stuff if one is using
CVS, but this seems unfortunate.  I wonder if there is some way to put
in configure.in a test to avoid evaling the transformed output 
of AM_PATH_GTK_2_0 if it does not get transformed, like

a=AM_PATH
b=GTK_2_0
c=$a_$b # avoid substitution
if [ "AM_PATH_GTK_2_0" != $c ]; then
  AM_PATH_GTK_2_0(blah blah)
else
  echo "warning: AM_PATH_GTK_2_0 not defined by aclocal, continuing
fi

I'd be stunned if this worked (not run), but thought I'd throw out the
idea.
