Redhat 7.0 sucks.  Please read <http://gcc.gnu.org/gcc-2.96.html> to learn
why. 

We have observed this behaviour from time to time with different versions
of GCC, but only with non-released ones.  Are you saying the error occured
in egcs-1.1.2 as well?  I'll have a look at what gcc-3.0 prereleases do
and maybe file a bug against it if it doesn't like matrix.h:144 either. 
In any case, I am pretty sure the error is not GiNaC's.

Just delete that default argument in matrix.h:143 and it should work for
you.  Or bootstrap a decent compiler (e.g. gcc-2.95.2) and use that one 
instead (but beware the ABI has changed, so you will have to recompile CLN
as well).
