To reproduce the original bug, you would need to build for
hppa64-hp-hpux11.31 target. If you bootstrap with an HP compiler,
you would need to add +DA2.0W to the stage1 CFLAGS. The two targets
use different math libraries.
The hppa64 problem was still present in my last build prior to
the lroundl issue. Somewhere between August 4 and 8 bootstrap
started to fail on this target.
I also still see the fails mentioned in comment #3. See
http://gcc.gnu.org/ml/gcc-testresults/2007-08/msg00236.html
This might be a different bug.
