problems building gcc - now current version

[Dave Lovelace <dave at fci dot izzy dot net>]

I posted something similar to this yesterday.  N8TM@aol.com, who is
apparently also tprince@computer.org, was kind enough to point out
that I was not working with the current rev.  Sorry - I got confused
by the sheer number of files on the ftp site.

I now have the current files, but the warnings and error look (to a
casual glance, anyway) to be the same.  Again, I hope someone can help.

I'm building gcc on a Data General AViiON (mc88100) running DG/UX R4.11MU06.
The compiler actually on the system (which came with the system) is
gcc; doing "gcc -v" yields:
gcc version 2.7.2 (m88k DG/ux, DG-2.7.2.11, Jan 18 1999)
The version I'm attempting to build is gcc-2.95.2.

I ran configure, which produced no alarming-looking messages.  I then
ran make bootstrap-lean.  It eventually produced some alarming-looking
warnings.  Then finally it errored out.  I'm attaching the warning &
error messages. I'm not sure how much of what preceded the final error
is necessary, so I'm including a bunch.

Thanks for any help anyone can offer.
