    SubjectRe: Patch to ask if user has egcs/pgcc / add me to credits
    Something I just realized...
    for pgcc/egcs: there are other flags like -mamdk6
    Doesn't this ask that we add another thing to the processor type so that
    there can be a -mamdk6 option to compile the kernel optimized for the AMD
    chips? (there may be other -m options too, I just know about amdk6)
