I believe we also use them to dispatch to xmalloc for hosts that cannot use malloc. Another issue that is gone for good with C++ - at least if you use 'new'. Existing uses already are there, so just go ahead. Support for constructing and destructing GC objects will be another story of course. Richard. >-- Gaby
