forth rep

seems to be fixed now. see the files forth.ss forth-tx.ss and
forth-rep.ss : the result of evaluating a (definitions . <code>) form
is an assembly code graph.

now, how to save the macro definitions so incremental compilation can
be performed? the 'definitions' macro should be extended with an input
assoc-list of defined words (and macros?).
