I think this is the patch that i was remembering:

Thu Apr  3 00:18:49 CEST 2003  Jan Hubicka  <jh@suse.cz>

        * i386.c (override_options):  Disable red zone by default on i386.
        (compute_frame_layout, ix86_force_to_memory, ix86_free_from_memory):
        Do not test TARGET_64BIT together with TARGET_RED_ZONE


I admit i never looked at the actual code, though, to be sure
of what it was doing.  When i saw that appear in the changelog,
i thought that it was a reaction to the bug that i had reported...
