The patch at <URL:http://gcc.gnu.org/ml/gcc-patches/2004-12/msg01174.html>
works for the test-case but gives regressions for mmix-knuth-mmixware compared
to a pristine "Thu Dec 16 00:49:58 UTC 2004".  I'm not too worried about the
fortran failures (since libgfortran still doesn't cross-compile for 64-bit
newlib targets with further missing functions when that's worked around),
but thought they were worth mentioning because they look easier to diagnose
than the execution failures.  Mike Stump:s contrib/compare_tests script says:

Tests that now fail, but worked before:

g++.dg/other/crash-2.C (test for excess errors)
g++.old-deja/g++.other/incomplete.C  (test for errors, line 14)
g++.old-deja/g++.other/incomplete.C  (test for errors, line 15)
g++.old-deja/g++.other/incomplete.C  (test for errors, line 16)

Tests that now fail, but worked before:

gcc.c-torture/execute/20040703-1.c execution,  -O0

and similar for the next four regressions there.
(These tests weren't error tests.)
