I did a 'cvs update', but didn't think to do a 'cvs update -d', and my tree was pretty old (because I only use it to do this) so config/accross.m4 and config/acx.m4 were not included in the regeneration.  If I regenerate with the updated tree, I get the same configure as I got for GCC.  This new configure differs from the current one by not having a --site-file flag, and in no other interesting way.

Ok.  I've now regenerated with pure 2.13.
