Note that when you run autoupdate on this, it will replace
AC_LIBTOOL_DLOPEN by _LT_SET_OPTION([dlopen]) in configure.ac.

Perhaps that could be changed to

AU_DEFUN([AC_LIBTOOL_DLOPEN],     
[_LT_SET_OPTION([dlopen])
AC_DIAGNOSE([obsolete],
[$0: Remove this warning when you adjust your code to use
      `LT_LIBTOOL_INIT([dlopen])'.])
])

Or something similar.  That way the AC_DIAGNOSE call in
configure.ac will remind the reader that something must be done.

(FWIW Autoconf has used this kind of AC_DIAGNOSE in several
macros, and CVS Autoconf recently switched to using the third
argument of AU_DEFUN -- my understanding is that this third
argument didn't work in previous version.)
