BTW, can you shed more light on the problem with 2.7.2? The C compiler seems to work fine, but C++ is not so good so far as iostreams was concerned. iostreams is incorporated into libc since C/C++ stdio have the same code base, but some symbols seem to not have exported, making it unusable to the point of not being able to compile the simplest "hello.cc". -- David Nugent: davidn@blaze.net.au, davidn@unique.blaze.net.au Unix/Linux/DOS/Win/Os2 Microsystem Technical Support [FOR HIRE!] http://www.blaze.net.au/~davidn
