Subject: Re: [PATCH] inet_ntop.c: Work around GCC 4.6's detection of uninitialized variables
Date: Tue, 18 Oct 2011 20:12:40 +0200	[thread overview]
Message-ID: <4E9DC198.9040108@gmail.com> (raw)
In-Reply-To: <7vehyagq82.fsf@alter.siamese.dyndns.org>

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.
