g++ -force_flat_namespace dies with multiple definition of symbols in libSystem
and crt3.o on Mac OS X 10.4.

I expected the link to succeed. This bug is also an Apple radar -

------- Comment #1 from geoffk at gcc dot gnu dot org 2006-05-03 17:12 -------
If fixed, this will be fixed in the Darwin linker. In the meantime, don't use
-force_flat_namespace. In fact, it's probably better if you don't use it at
all; the system libraries aren't expecting it and this is just one of many
possible problems.

------- Comment #2 from pinskia at gcc dot gnu dot org 2006-05-03 23:34 -------
Can we then have a new cctools which includes a newer ld64 also since right now
powerpc-darwin is broken on a G5 without using --disable-multilib.

This specific problem should be resolved with Xcode 2.3, just released.
However -force_flat_namespace still doesn't work.
