Subject: configure: Modify detection of supported warning options
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=bd947d30b6757067fa8f8407ef248fd8645383ee;p=qemu-xen-4.6-testing.git

configure: Modify detection of supported warning options

Reversing the order of the warning options and -Werror is important
when clang is used instead of gcc. It changes nothing for gcc.
