You can actually do this through the Win32 API: see the FILE_FLAG_POSIX_SEMANTICS flag for CreateFile. However, MS realized this was a security problem, so as of WinXP, this option will in normal circumstances do absolutely nothing. You now have to explicitly enable case-sensitive support on the system for either the "Native" or Win32 APIs to allow it.

(the SFU installer asks if you want to this, but even SFU has no special dispensation)

Another trick you can use with CreateFile is to start the filename with \\.\.
If that is done, the only processing done on the filename before CreateFile
calls NtCreateFile with the name is that \\.\ is replace with \??\, which is
an alias of \DosDevices\.
