Example of debugging GCC with toplevel bootstrap

[Richard Kenner]

    MRS and Eric Botcazou objected strongly against not being able to
    build a 1-stage GCC with --disable-bootstrap.  And that's never going
    to happen.

One would hope that wouldn't, but what I heard was an objection
against removing what's there now, namely the capability to bootstrap
GCC and *just* GCC.  In other words, to have a mode when you can do a
bootstrap that does no more work than the present one does.
