/dev/null works on UNIX, on Windows it's nul (and does not appear in
the filesystem).  However, another nice solution would be to walk
through the path (os.getenv("PATH")).  With other words, write a
function which does the same as the UNIX which command.

Note that paths are separated by ";" on Windows instead of ":".

  Reinhard
