From c04e0a08c9ced78d9a762969c584e64b5eca1d7a Mon Sep 17 00:00:00 2001 From: Jeff Johnston Date: Fri, 13 Dec 2002 17:55:49 +0000 Subject: [PATCH] 2002-12-13 Jeff Johnston * defs.h (init_last_source_visited): New prototype. (add_path): Ditto. * source.c (add_path): New function that adds to a specified path. (mod_path): Change to call add_path.
