From e9fcf7ea8839c38acdc9ae4b32d8b3a3dfd6af87 Mon Sep 17 00:00:00 2001
From: Roland McGrath <roland@redhat.com>
Date: Tue, 12 Dec 1995 03:31:40 +0000
Subject: Use plain stat instead of safe_stat. (find_semicolon): Function
 removed. (read_makefile): Don't use find_semicolon or remove_comments for
 rule lines. Use find_char_unquote directly and handle quoted comments
 properly. (multi_glob): Call dir_setup_glob on our glob_t and use
 GLOB_ALTDIRFUNC flag.
