  configure: WARNING: X11/extensions/multibuf.h: present but cannot be compiled
  checking X11/extensions/multibuf.h presence... yes
  configure: WARNING: X11/extensions/multibuf.h:     check for missing prerequisite headers?
  configure: WARNING: X11/extensions/multibuf.h: see the Autoconf documentation
