OK, so posted in correct format.

BTW, Geoff, sorry if I misidentify his problem.  He reported undefined
labels on sparc-sun-solaris2.9 once PCH was enabled in libstdc++-v3.
Looked like the same issue I'd seen on our dwarf2 platforms but then I
noticed that sparc-sun-solaris still uses (conditionally) dbxout.c.
Oh well, that port may still have a problem since I don't know how it
was building/testing libstdc++-v3 (I can't imagine that it is
multilib'd on debugging format alone; but 64-bit sol2, which was a
multilib option last time I built sol2, uses dwarf2 unconditionally
there so maybe that was the source of the reported failures).
