Version 1.51
------------
Fix memory leak in statfs when mounted to very old servers (e.g.
Windows 9x)
Windows 9x). Add new feature "POSIX open" which allows servers
which support the current POSIX Extensions to provide better semantics
(e.g. delete for open files opened with posix open). Take into
account umask on posix mkdir not just older style mkdir. Add
ability to mount to IPC$ share (which allows CIFS named pipes to be
opened, read and written as if they were files).
Version 1.50
------------
