Unfortunately, for my original example, this seems to have made things worse.
The differences are:

  $ diff -w ../old/z.m ../new/z.m
  6,8c6,7
  <   Special opcode 234: advance Address by 16 to 0x80483c1 and Line by 5 to 13
  <   Advance PC by constant 17 to 0x80483d2
  <   Special opcode 34: advance Address by 2 to 0x80483d4 and Line by 1 to 14

I.E. gcc now associates the code to print the results with line 8 instead
of line 13.
