Since 0905 the following patch is in:
Fri Sep  5 07:35:16 CEST 2003  Jan Hubicka  <jh@suse.cz>

        * opts.c (decode_options): Enable unit-at-a-time at -O2.
        * params.def (max-inline-insns-single): Set to 500
        (max-inline-insns-auto): Set to 150
        * invoke.texi (max-inline-insns-single, max-inline-insns-auto): Update.

So, it seems that the new heuristics fixed it.

Gunter didn't use "current mainline" but something older,
