C++ Streams and the underlying file descriptor

[Martin v. Loewis]

If you compile the current CVS libstdc++ with _STREAM_COMPAT, you get
a filedesc() method on an fstream object, returning the file
descriptor. Alternatively, you can use fstream::rdbuf()->fd()
(which filedesc() is a short-hand for).
