Shouldn't LIBXMLCPP_EXCEPTIONS_ENABLED be defined?

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

After the --disable-api-exceptions configure option was removed (commit 
81fead80bc5d0cc6f6188fd2d0f883def0e9a01e), LIBXMLCPP_EXCEPTIONS_ENABLED 
is not defined in libxml++/config.h.

Application programs that contain code such as

  #ifdef LIBXMLCPP_EXCEPTIONS_ENABLED
  try
  {
  #endif //LIBXMLCPP_EXCEPTIONS_ENABLED
    .........
    .........
  #ifdef LIBXMLCPP_EXCEPTIONS_ENABLED
  }
  catch (const xmlpp::exception& ex)
  {
    std::cout << "Exception caught: " << ex.what() << std::endl;
  }
  #endif //LIBXMLCPP_EXCEPTIONS_ENABLED

will not catch exceptions.

Compare e.g. glibmm. glibmm/configure.ac contains
  AC_DEFINE([GLIBMM_EXCEPTIONS_ENABLED],[1], [This is always set. This 
is only for backwards compatibility.])
and GLIBMM_EXCEPTIONS_ENABLED is defined in glibmm/config.h.

Shouldn't libxml++/configure.ac contain
  AC_DEFINE([LIBXMLCPP_EXCEPTIONS_ENABLED],[1], [This is always set. 
This is only for backwards compatibility.])
until the next API break?
