Both flages fixed the problem.

I'll give it a try. How about on the command line? I'll have
to try that tomrrow afternoon. Sleep now!

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.

I 'made distclean', './configure --verbose >&logfile', added
#define DWARF2_UNWIND_INFO 0 to gcc/tm.h, 'make bootstrap-lean >>& logfile &'
and then went to sleep. Imagine my surprise when I get to work and 'tail -f
logfile' gave me the same errors as before. Is there any other way to disable
the DWARF2 exceptions?

I have been known to tinker with MIPS parts, but I think I recognize
the symptoms in your case.

I think you're getting nailed by the same thing that got the OpenServer
COFF port. You're getting DWARF2 exceptions (you'd have to look at the
generated assembly to be sure) and they're emitting constructs like
this, but the assembler is unable to handle the subtraction of the
forward references. You can roam through the archives for conversations
on this topic.
To prove or disprove this theory, try the following, in decreasing ease:
Manually compile with file with either -fno-exceptions which
turns exceptions off completely.
Compile the file with -fsjlj-exceptions to force the use of
the setjmp/longjmp exceptions.
Install GNU as.
If either of these work, this is very likely your problem. From here,
your options would include:
Using the GNU assembler for your target.
Experimenting with disabling the DWARF2 exceptions by adding a
#define DWARF2_UNWIND_INFO 0
in your tm.h file
(remember to make clean and rebuild) This is the
approximate equivalent of the -fsjlj-exceptions flag.
Getting the dwarf2 code to not emit forward refs.

Ok, the code for enquire.c is of course fine, a gcc -c enquire.c proves
this. looking through the logfile of the build it would seem that
enquire is the first bit of code compiled with the first stage
compiler, so that means that the first stage compiler wasn't built
properly (pretty obvious). I tried the offending command again, this
time with the verbose option (see below). Any help, hints, comments?

It would appear that some recent changes to enquire.c breaks egcs
for ultrix 4.4 since I can no longer get it to build even the first stage.
I used a 'configure; make bootstrap-lean' on a freashly unpaced 970929
distribution using gcc 2.7.2.3 and g77 0.5.21 and got the following
error messages. Since I am only an amateur hacker I have absolutly no
idea what these errors mean. Any comments, help or suggestions?
