Update of /cvsroot/scsh/scsh-make
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv32640
make-rule now uses the sort function of dfs, added the predicate
function position< therefore and changed the rule-node/sort-msgs
fixed rule-node/make: now prereqs-results is checked for being an
empty list -> init-state is now passed properly, prereqs-results are
well-formed now. apply is only used for non-empty prereqs-results
(then the number of prereqs is unknown here).
