Status and rationale for toplevel bootstrap (was Re: Example of debugging GCC with toplevel bootstrap)

[Richard Kenner]

    Then it seems to me that you are just relying on a peculiarity of the
    Ada build system, that is the fact that you can work entirely from
    within the GCC directory.

That's by design, of course.

    What you need to do then, is to run from the toplevel "make
    stage3-bubble; make -C gcc gnatlib_and_tools".

Does the latter differ from "cd gcc; make gnatlib_and_tools"?
