Subject: [PATCH] clients/stacking: Silence a compiler warning
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This patch fixes a compiler warning when building with
clang, since it doesn't support gnu_printf attribute.

v2:

 - Switch to WL_PRINTF per suggestion from Eric Engestrom.

v3:

 - Explicitly include wayland-util.h
