Jup, that's it. With `mawk', it seems it's always missing the last
byte of the pass name. This is (one small fragment of) the diff
between gawk and mawk output:

-         NEXT_PASS (pass_forwprop, 1);
+         NEXT_PASS (pass_forwpro, 1);

All other content is wrong in the same way. Maybe they're counting the
line terminating '\n' differently?
