I have used realpath to canonicalize the following path:
  c:foo\bar
The working dir on drive c: is the root dir.  realpath
returns:
  c:\/foo/bar
The leading slash will always be added by the calling __canonicalize_path()
function and the backslash that is returned by int 0x21 function 0x7160
is superlfluos.
The patch below will fix this.

Regards,
Juan M. Guerrero
