Update from Ralf Corsepius:

  Yep, I have a bunch of bug-fixes and additions pending (Yet another monster
  patch, ... I can hear you scream :-).

  1) configure.in : one AC_CONFIG_HEADER(...) line too much.

  5) configure.in: --enable-cpp should probably be renamed to --enable-cxx, as
  gnu-programs use "cxx" to specify C++ specific configure options, while cpp
  is used for the preprocessor (e.g egcs uses --with-cxx-includedir, autoconf
  internally uses $CXX),
