autoconf, automake and friends

[Olivier]

This is not really a gcj question. 
I've tried to adapt your example to my 'Makefile.am' but it won't let
me use VPATH! actually, automake let me use it, I can see it in
'Makefile.in' but 'configure' insist on removing it from the final Makefile!

Is there a reason for that?

Olivier

PS: should I persevere with auto friends? It does not seem to
help much for java.
