Oh boy.  I didn't even know that NT allows that.

That's two bugs in one.  The lilypond package has paths with leading
"./" in it, and setup.exe does not recognize that and remove the dot
path.

For now I have removed the latest lilypond package from the distro.
Jan, can you please fix your package not to have leading ./ in the path?

As for setup.exe, I have to have a look how to avoid that.

What you can try to get rid of the directory is this:

  del \\?\M:\.
  rmdir \\?\M:\.

If that doesn't work, maybe there's a chance to rename the directory
using the \\?\fullpath syntax.  Or, if that doesn't work, maybe you
can at least move the files out of that dir.
