AFAIK mips-dec-ultrix is not supported in newer versions of gcc any more.
So I did not try it, but was finally able to build gcc-2.95.3 with the
following changes (and with ANSI C, i.e. CC="cc -std1"):

   gcc/configure   (line 6078, 6080, 6082, 6159: ... test -x ...)
   gcc/cp/Make-lang.in   (line 169: ... [ -x ...)
   gcc/fixinc/fixincl.sh   (line 77, 100, 102: ... test -x ... [ ! -x ...)
   (void *) cmp_combine_givs_stats
      gcc/loop.c   (line 7044, 7285, 7459)
      texinfo/makeinfo/makeinfo.c   (line 8225)
   _IO_pos_t -> _IO_off_t
      libio/genops.c   (line 470, 473, 554, 885)
      libio/fileops.c   (line 422, 590)
      libio/ioseekoff.c   (line 28)
      libio/ioseekpos.c   (line 28, 31)
      libio/strops.c   (line 208)
