I think this patch was actually from the gcc stream that Kenner was working
on.  I have a patched version of gcc-2.8.1 that works reasonably well under
VAX Ultrix 4.3.  It also has g++.  I was never able to successfully build
2.95 under Ultrix 4.3.  Congratulations!

Rather than back porting this patch, I think it would be better to get
the current mainline code working.  I am able to build the C language
sucessfully with gcc but there are still problems with a g++ stack
overflow building libstdc++.  There are a couple of patches pending
that enable one to get this far.  With the native cc, there are a whole
bunch of enum comparisons that still need to be fixed.  This is straight
forward but tedious.  You need a recent version of binutils.  This
fixes a long jmp problem that you will encounter building expr.c.
