Huh. POWER5 certainly ought to be good with lwsync. I think the lwarx
hint bit doesn't do anything on POWER5, but it's not supposed to cause
problems either.

If you can try the same build there and see whether it works, that would
be useful information; but we'd like PG to work on POWER5 too ...

I'm stumped then. Maybe the problem is something else entirely.
Could you look at the assembler output file and see exactly what
lines it's complaining about? If the temp file is not left
behind by a normal build, do the failing gcc call over again
manually, substituting -S for -c so you get a .s file as output.
