include/tst_timer.h is broken on gcc 4, which we have in Travis (CentOS 6).
I don't know how to fix this, but maybe fix is trivial.
Or is it time to finally drop this oldest distro? If it's easy to fix, I'd
postpone dropping CentOS 6 after release (some embedded distros/projects might
still use old compilers).
