libntfs compiles fine using cygwin, it doesn't with
mingw and I think it will compile with MSVC++.
I think it's easier to port libntfs to mingw than to MSVC
or even easier use cygwin!

To list NTFS files, you really need libntfs if you open
PhysicalDrive0. But there are Windows functions to list
files that doesn't require direct disk access.

No, TestDisk uses libntfs for that purpose.
