    Not all of them are applied on x86:
    % cat stamps/02-patch-stamp-*|less
    bootstrap patches applied.
    cpp-dos-newlines patches applied.
    cpp-macro-doc patches applied.
    gcc-cvs-updates-20000220 patches applied.
    gcc-default-arch patches applied.
    gcc-empty-struct-init patches applied.
    gcc-manpage patches applied.
    gcc-pointer-arith patches applied.
    gcj-debian-policy patches applied.
    gcj-vs-iconv patches applied.
    gpc-2.95 patches applied.
    gpc-updates patches applied.
    libg++-update patches applied.
    libobjc patches applied.
    libstdc++-bastring patches applied.
    libstdc++-out-of-mem patches applied.
    libstdc++-wall3 patches applied.
    libstdc++-wstring patches applied.
    reporting patches applied.

    And only 4 have any chance to be relevant: gcc-cvs-updates-20000220,
    gcc-default-arch, gcc-empty-struct-init. Unfortunately, the first one
    is ~100Kb worth of changes. Hmmm... After some cleaning the whole thing
    boils down to 11Kb. And I seriously suspect that relevant bits are
    in cse.c, loop.c or toplev.c, with the first two being the most likely
    candidates (all coming from the -cvs-updates-20000220)...
