You mean POSIX_FILE_SEMANTICS?  Haha, nice laugh.  It doesn't, in any 
useful way.  That code was put in for NT 3.1 to pass some government 
requirement and has completely bitrotted ever since.  Hell, it doesn't 
even support directories! (Don't even mention posix modules.  Unless you 
want to write 'cat' they're totally useless.   Why do you think the 
cygwin people haven't done it?).

The only thing that that registry entry does is un-breaks the Windows 
2000/XP system so that it makes it possible to do case sensitive calls 
*at all*.  I set that during the installation of the driver.  By itself 
it isn't remotely useful.

The underlying NTFS system is case sensitive (or can be) and by 
translating the calls where necessary it can be done relatively easily. 
    There is no other way to do it really.
