CORRECTION, you are getting warnings.  For the most part you can ignore warnings.
The fix you need to worry about is for the assembler.  Otherwise you won't be
able to compile gcc-2.3.3 at all.  BTW, the PTF is U409205 for the assebler fix.

	There is one change in cse.c at about line 3200 or so under  case SMAX. as below

 case SMAX:
          if (width <= HOST_BITS_PER_WIDE_INT && GET_CODE (op1) == CONST_INT
              && INTVAL (op1) == (unsigned) GET_MODE_MASK (mode) >> 1
                                 ^^^^^^^^^^
              && ! side_effects_p (op0))
            return op1;
          else if (rtx_equal_p (op0, op1) && ! side_effects_p (op0))
            return op0;
          break;

Add the unsigned typecast to GET_MODE_MASK.  You'll need this if you want to compile
groff some day and who knows what else.  That's all I know...
