(tree_identifier::eval (int, int, const Octave_object&): And here. * tree-expr.cc (install_nargin_and_nargout): New function. * tree-expr.h (tree_function::tree_function (tree_statement_list *, symbol_table *, int, int)): Call it. * tree-expr.cc (tree_function::bind_nargin_and_nargout): New function. (tree_function::eval): Call it insead of the one from variables.cc. * variables.cc (bind_nargin_and_nargout): #if 0 out.

Use kpathsea.a, not libkpathsea, so we don't have to modify the kpathsea Makefile.
