Folks,
I'm seeing these warnings on the mac os when building hwloc-2.0rc1 with clang:
----8<----

lstopo.c: In function 'usage':
lstopo.c:425:7: warning: "CAIRO_HAS_XLIB_SURFACE" is not defined, evaluates to
0 [-Wundef]
#elif CAIRO_HAS_XLIB_SURFACE && (defined HWLOC_HAVE_X11_KEYSYM)
^~~~~~~~~~~~~~~~~~~~~~
