Subject: configure: Fix set-but-not-used warning in Xen 4.1 probe
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=9b4c0b56b5f0b341ffa41238e3d2e96ec3b031d9;p=qmiga%2Fqemu.git

configure: Fix set-but-not-used warning in Xen 4.1 probe

The Xen 4.1 probe never uses the return value from xc_interface_open(),
so was provoking a compiler warning on newer gcc. Fix by not bothering
to put the return value anywhere.
