When I look at a C compile on Linux (with GCC 4.1.1 or with GCC ToT) on
x86, I see a link line containing:

-lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s
--no-as-needed

So it looks like GCC is going to use the static libgcc first and include
the shared libgcc_s only if needed, this may be why Linux doesn't have
the same problem as HP-UX with libgomp.   The HP linker that I am using
on IA64 HP-UX doesn't have an --as-needed flag.  I guess I could leave
it out and use "-lgcc -lgcc_s" on HP-UX.
