From 75018ad0cc532ff5971219e82b87d1bfdafa101a Mon Sep 17 00:00:00 2001
From: James Peach <jpeach@samba.org>
Date: Tue, 24 Oct 2006 03:23:19 +0000
Subject: r19477: Patch from Huang Dejin Eugene <hdejin@yahoo.com>.

Add configure option --enable-fam so that FAM support can explicitly
be controlled at build time. Default behaviour is to autodetect.
(This used to be commit 066951bc48723b1a26aab9ebb21ff2c897189043)
