I'm testing a fix for the first one, which results from changes to
libgcc2.h.
I'm planning to send it to gcc-patches when my bootstrap and test run
finish.
If you want I can send it to you earlier; the build has gotten past libgcc,
and I've successfully done a cross compile from i686-linux.

I've been building with CXXFLAGS="-O1 -g" on ia64 recently because
otherwise
there's an ICE in dwarf2out.c.  I think that's a known problem that was
discussed a month or so ago.
