I think you mean that you mean the SUBDIRS directive should be enabled 
again and the respective _SOURCE _LDADD BIN_ LIB_ directives should move 
 to the subdirecties makefile.am?
That was the path I had taken earlier and it was the same (worse 
actually) misery as I'm currently in.

If you don't mind, I would really like to see an example of your 
configure.ac and makefile.am files as reference. The examples in the 
automake manual are just too trivial for my taste. I really don't have 
any clue in how to get this thing to work.

Thanks,
