Yep.

My assumption here was that if you said "make install" then the
next time you ran "javac" you'd be getting the one you just installed,
so that "$objdir/..../javac" and "javac" would run the same code.
A larger problem is that the dependencies are recursive, so you can never
really be sure, eg.
Klasses.jar depends on:
- the classes used by the compiler to build it (including Klasses.jar)
- the java runtime used to run the compiler
Kaffe and kaffeh depend on:
- the derived header files
The derived header files depend on:
- Klasses.jar
- the version of kaffeh used to generate them
Etc..
That's why to me the easiest thing is to just run some automated
script that rebuilds, reinstalls, and regenerates everything a few
times, then saves it :-)
By the way, if you want to tweak more Makefiles or whatever while
this discussion is still fresh please go ahead because I've gotten
busier with work this past few days and it make take a while before
I can work on them.
