Actually I think this is not precisely true. For all practical purposes this 
is a correct description of NTFS as it is presented by the windows API. The 
filesystem is case sensitive with respect to its data structures. Nearly the 
whole windows API presents it as being case insensitive but case preserving. 
This is due to the implementation of name matching, to me the name matching 
is not conceptually part of the filesystem. Furthermore even in the windows 
API there are means for case sensitive access (see attached code).

Sure you can.

No you don't have to use the POSIX subsystem.

Have a look at the attached program. Compile (SUBSYSTEM:console) and run. It 
will create two files with filenames differing only in case. BTW this only 
works for NTFS (i.e. not for network shares).
