From ef5dc55983b5786d602688a596ea349b0dfdc0c8 Mon Sep 17 00:00:00 2001 From: Michael Adam Date: Thu, 24 May 2007 15:51:01 +0000 Subject: r23118: Make inet_pton and inet_ntop available through lib/replace. The code for inet_pton.c and inet_ntop.c is taken from the rsync code. I will put this into 3_0 and 3_0_26 too, but let's sort the readahead issue in lib/replace of 3_0 first...
