for getting the list of variable names and for clearing all rule and variable storage. * compile.c - better error reporting for unknown rules; now it is a hard error. * hash.c/h - added hash_free to allow removal of elements from a hash * rule.c/h - implemented rule freeing; stopped exporting rules to the global module by default. * variable.c - reclaim variable storage when disposing of variable hash. * build.jam - make grammar building work under NT [SVN r18405]
