[Spice-devel] [PATCH spice-streaming-agent v2] Eliminate signed/unsigned warning

[Frediano Ziglio]

From: Christophe de Dinechin <dinechin at redhat.com>

Currently -Wsign-compare is disabled by default in the default settings
(m4/spice-compile-warnings.m4).
However is good and not that expensive to remove this warning.
