gentoo-overlay/net-libs/zeromq/files/zeromq-3.2.3-unused-variable.patch

Fix building with -Wall.

Description from upstream repo:
    Author: Pieter Hintjens <ph@imatix.com>
    Date:   Wed Jan 30 23:53:23 2013 +0100

        Various cleanups to test programs
        
         - Patch applied using git am from libzmq commit 5f009e52
         - tests/test_raw_sock.cpp doesn't exist in zeromq3-x, so that
           file was manually removed from the patch before 'git am'
