function position< therefore and changed the rule-node/sort-msgs
function accordingly.
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).
macros.scm and rule-trans-set.scm
rule-trans-set.scm: known-rules-update is now really ugly! (but working)
will be replaced with topological sort
known-rules-update now loops until there are no
further changes in the rule-candidates-list (each
time). this should really make it work now.
makros.scm replaced with macros.scm
macros.scm: in make-is-out-of-date? there was no check for
file-existence of each prereq
