This would be done with passing "--disable-fatal-warnings" to
./configure invocation.

Note that such build failures will also go away once you try
with libqb <= v1.0rc1, i.e., anything that doesn't include
https://github.com/ClusterLabs/libqb/pull/175 (736e2c8).

But both will just fool yourself into thinking that Pacemaker
always passes logging parameters per the format strings (and
hence segfaults due to such mishandlings are not possible),
which is not the case until the changeset Lars referenced.

So actually using recently released Pacemaker-1.1.15-rc1
(which includes that) might be a better idea.

Hope this helps.
