Subject: [PATCH] Building fix about implicit declaration of strnlen
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

I got build failing as below:
cc1: warnings being treated as errors
gdhcp/client.c: In function ‘alloc_dhcp_option’:
gdhcp/client.c:1455: error: implicit declaration of function ‘strnlen’

define _GNU_SOURCE fixes this problem.
