RE: True case-sensitive filenames

["Sergey Okhapkin" <sos at sokhapkin dot dyndns dot org>]

I don't understand the proposed algorythm. Anyway the only way to rename
the file on windows (without create new file/copy old to new/delete old
file schema) is RenameFile() call. The call is case-insensitive. If you
have files "a" and "b" in the same directory how to rename "b" to "A"?
RenameFile("b", "A"); removes file "a":-(
