From 1f343c7a0f9937c7bc5c8fee67f33850699b68f4 Mon Sep 17 00:00:00 2001
From: "Todd C. Miller" <Todd.Miller@courtesan.com>
Date: Fri, 24 Mar 2000 01:23:05 +0000
Subject: [PATCH] If there is no inet_addr but there *is* an __inet_addr that's
 ok since inet_addr is probably just a macro then.  The better thing to do
 would be to look for the macro, but this is fine for now.
