OK, I finally reran the tests and looked at the log.  There are several types of
problems, and I'll give some examples of each.  This was configured on
solaris2.8 with --enable-checking=no, and tested with '-mcpu=ultrasparc -m64".

I don't understand this type of problem:

<problem>

There is one other type of internal error:

<problem>
spawn /export/home/sources/egcs/solaris-2.8/gcc/g77 -B/export/home/sources/egcs/solaris-2.8/gcc/ /export/home/sources/egcs/gcc/testsuite/g77.f-torture/execute/19990826-2.f -w -O1 -mcpu=ultrasparc -m64 -L/export/home/sources/egcs/solaris-2.8/sparc-sun-solaris2.8/libf2c -lm -o /export/home/sources/egcs/solaris-2.8/gcc/testsuite/19990826-2.x

</problem>

The vast majority of the extra problems are similar; did something not get built
or multilib'ed?:

<problem>

</problem>

And another:

</problem>

and, quite often:
