The difference is that the twists up to this point have been spread
everywhere.  All through the configury, all through the makefiles.

The approach that Mark et al proposed and that I implemented doesn't
require constant tweaking, like the current situation.  It doesn't need
to be constantly tested.

To remind the audience, what we're talking about had some discussion here:

    http://gcc.gnu.org/ml/gcc-patches/2002-04/msg00866.html

and some patching here (note this was before the top-level autoconfiscation):

    http://gcc.gnu.org/ml/gcc-patches/2002-04/msg01001.html


I like the idea of making our configury simply require/assume separate
build dirs, but there's no need to reject an in-srcdir *interface* just
because maintaining a parallel in-srcdir *implementation* has been a PITA.
