Is a byte meant to be treated as signed? It's probably worth making that explicit so scheme level stuff doesn't depend on the vagaries of C type conventions. _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel
