umm, sure it is.  if dirname/basename don't handle the OS separator, then
where do you think it should be handled ?  every place that calls basename ?

GNU/POSIX not talking about it isn't terribly relevant -- they don't care
about systems like Windows that have diff path name semantics.

although it's a moot point if you move everything to gnulib as they handle
the issue properly.
