>>> "NTFS supports two slightly different modes of operation that can be selected by the subsystem of the application interacting with NTFS. The first is fully case sensitive and demands that file names supplied by the application match the names stored on disk including case if the file on disk is to be selected. The second mode of operation is case preserving but not case sensitive. This means that applications can select files on the disk even if the supplied name differs in case from the name stored on the disk. Note that both modes preserve the case used to create the files. The difference in behavior noted here applies only when an application needs to locate an existing file. POSIX takes advantage of the full case sensitive mode, while MS-DOS, WOW, and Win32 subsystems use the case insensitive mode."

That looks ok. However, this doesn't solve existing or future
repositories - unless this is applied by default or the default
triggers a warning :)

Perhaps if it is possible, svn on windows can use the posix api? - I
don't know how that works :)
The microsoft article linked a few mails back by Bob Archer states
that using the posix api it is possible to have cased file-names and
