I didn't even have an old bootstrap of the trunk for HP-UX; I tried to do
one and it died with

This is of course completely unrelated to Geoff's patch.

The context around the abort reads
4825 {
4826 /* Some object formats don't support named sections at all. The
4827 front-end should already have flagged this as an error. */
4828 gcc_unreachable ();
4829 }
so evidently something is trying to use a named section on a platform that
does not support it.
Here's more backtrace. I have a somewhat older gdb (6.0), so not sure if
the next message matters. The section name is ".text.unlikely".
During symbol reading, block end address 0x2e6161 less than block start address
0x2e6170 (patched it).
During symbol reading, block end address 0x2f10c1 less than block start address
0x2f10e0 (patched it).
