Exceptions worked fine for me in m68k-elf in the CVS archive not two
weeks ago.

You should find that if you are using ELF, and if you are calling the
.init section in your crt0, that exception handling works in the
current CVS, using DWARF-based exceptions.  If you're _not_ using ELF,
I would strongly suggest you switch.

It may well be broken in the released 2.95.x versions, I would suggest
using the CVS or a recent snapshot.
