OK.   This means the code your assembler is finding offensive is
related to exceptions - just like the situation I ran into recently.

It really shouldn't be too painful.   Ultrix is listed as a supported
target in current GAS.

If we all did that, you'd be a little less close to getting your target
to work again, now wouldn't you? :-)

Don't know of a way to do that.    If you specify the flags described
above you'll force either no exceptions or non-dwarf2 exceptions.  

As a kludge, you can change it from '1' to '0' at the end of gcc/defaults.h.
