From 7b8da9264b24e06711c13642e9cbbdb8cec95360 Mon Sep 17 00:00:00 2001
From: Jim Meyering <jim@meyering.net>
Date: Fri, 2 Nov 2001 13:16:10 +0000
Subject: (dev_ino_pop): Cast 2nd arg of obstack_blank to `int' before negating
 to avoid warning from gcc on systems with 64-bit size_t.

Rename global: s/trace_dirs/recursive/.
(extract_dirs_from_files): Rename parameter:
s/recursive/ignore_dot_and_dot_dot/.
