I think we're almost there... we should light a beacon or something
when the rest of kaffe-core can tune in again on this channel...

(hopefully) no: the header files won't be derived files anymore, they will
be created on the fly during a normal build from the existing Klasses.jar.

No. That would be silly.
(c) is implemented by modifying the Makerules to use the built kaffe
and the built libraries in the object tree --- note that's *only* for
this stage, not for the first stage where the preexisting tools are used.
This second pass does not depend in any way on what's installed where.
As for the question whether your preexisting tools are overwritten,
that entirely depends on whether your specified installation target
(--prefix) would override the "pre-existing" tools.
What is pre-existing and what isn't is decided at configure time, either
using your path or some environment variables. So, yes, if you tell
kaffe at configure time to use your old javac from your installation
target as "pre-existing tools", then make install will overwrite it.
