I am trying to install gcc (version 1.37.1) on a DS3100 (Ultrix 3.1)
and seem to be having a problem.  When I compile the distribution
using the Dec/MIPS cc I get the following error messages.  The
documentation suggests that the first is to be ignored and I'm sure
the third is irrevelant, but I am less sure of the second.

cc  -I. -I. -I./config -c insn-emit.c
ccom: Warning: insn-emit.c, line 729: statement not reached
        operand0 = emit_operand[0];
      ----------------------------^
ccom: Warning: insn-emit.c, line 749: zero or negative subscript
        rtx emit_operand[0];
      --------------------^
make hard-params
cp ./hard-params.c . > /dev/null 2>&1
*** Error code 1 (ignored)

Upon recompiling gcc with itself I cannot use the -g switch as
suggested since the following message results:  cc1:  Invalid option
`-g'.  I assume this is related to the comment in the documentation
about "GNU CC cannot generate debugging information in the unusual
format used on the Mips."  Without -g everything recompiles just fine
with gcc.

To test the results, I recompiled it with gcc a second time following
the instructions in the documentation.  Upon comparing the resulting
files, however, I find differences between files.  Differences arise
whether or not I use the -g option in the original compilation with
cc.

Does this mean that errors exist in my compiled version of gcc?  I
would appreciate any suggestions you can make, especially it you have
successfully installed gcc on a DS3100.  Thanks in advance.
