From: Juergen Beisert <juergen@kreuzholzen.de>
Subject: Avoid some confusing compile time warnings

We are compiling ntpclient on a GNU based system. This patch avoids the
following warning:

ntpclient.c:447: warning: implicit declaration of function 'herror'
ntpclient.c:447: warning: nested extern declaration of 'herror'

Signed-off-by: Juergen Beisert <juergen@kreuzholzen.de>
