Subject: Enforce zero warnings
X-Git-Url: http://rtime.felk.cvut.cz/gitweb/jailhouse.git/commitdiff_plain/cf123b368412c9d7f1efcb5a7d3e6f4f5ba990a5?ds=sidebyside

Enforce zero warnings

Break the build in case of warnings. Can still be temporarily
overwritten by appending EXTRA_CFLAGS=-Wno-error to a build.
