Hi, My DSP compiler comes with an ancient version of STL which only has old-style streams support (non templated streambuf etc.). It seems that in order to use some parts of boost that use streams, I would need to either modify boost to allow old style streams or use something like STLPort to get a more modern version of STL (My compiler vendor is unlikely to provide me with a more modern version). Using STLPort comes with its own porting issues - I have tried it briefly and it could probably be made to work but it would definitely require some modification. Is there any interest in supporting old-style streams in boost? Andrew
