message:
  Make 'configure' work out-of-the-box on Solaris.
  
  * configure.ac: Work even if libgif etc. are missing.  Emacs works
  without these libraries even if its default GUI is harmed, so they
  are not strictly necessary.  Another possibility would be to
  disable X11 if these libraries are missing.  The point is that a
  plain 'configure' should not fail on platforms like Solaris 11
  where one or more image libraries are not installed by default.
