Subject: [PATCH] inet_ntop.c: Work around GCC 4.6's detection of uninitialized variables

From: Sebastian Schuberth <[email-masked]>
Date: Tue, 18 Oct 2011 18:25:50 +0200

GCC 4.6 claims that

    error: 'best.len' may be used uninitialized in this function

so silence that warning which is treated as an error by also initializing
the "len" members of the struct.
