Yep.

Which is as expected.

a default.exp that loads "standard.exp"

I don't think so. How do I set DEJAGNU correctly?

Ok. You'll need 
to cvsupdate -d in the libstdc++-v3 source directory, apply this patch, 
and then rebuild the autoconf/automake bits.

I just checked in the bits for the new harness, but did not activate
them. Here's the patch to do so. After applying, you'll need to do

aclocal; autoconf; autoheader; automake

at the top level of the libstdc++-v3 source directory.

To avoid confusion, and to allow the new harness to be used without
destroying the old one, DEJATOOL changed to libstdc++-v3. So,
libstdc++-v3 type bits are the ones that you'll want to pay attention
to in the testsuite.

Thanks again for your help.

Here's the patch:
