  # The rest of this file is basically the concatenation of libtool.m4 and
  # ltdl.m4 from the libtool 1.4.2 package. Also pkg.m4 from the pkg-config
  # 0.20 package. However, to work around a missing AM_CONDITIONAL macro,
  # Bryce made the following change:
  #
  # Change these lines
  # AM_CONDITIONAL(INSTALL_LTDL, test x"${enable_ltdl_install-no}" != xno)
  # AM_CONDITIONAL(CONVENIENCE_LTDL, test x"${enable_ltdl_convenience-no}" != xno)
  # to this
  # if test x"${enable_ltdl_install-no}" != xno; then
  #   AC_DEFINE(INSTALL_LTDL)
  # fi
  # if test x"${enable_ltdl_convenience-no}" != xno; then
  #   AC_DEFINE(CONVENIENCE_LTDL)
  # fi
  #
  # There is probably some way to get AM_CONDITIONAL defined, which would
  # be better.
