Manfred -- What was the failure mode?  Mis-compiled code, compiler
abort, etc?

The only unrolling bug we've fixed recently was a problem with
find_splittable_givs trying to split givs with a dest_reg that was
created by loop.
(which could cause either a segfault in unroll, or incorrect code).

We fixed this in egcs back in late Nov.  I can forward that fix to
gcc2 if the maintainers want to look at it.
