Incompatibility CDPATH, ash, sh, porting from *nix

Hint for porting *nix software -

---

There is a known problem with ash or something like because DPATH will have *ix semantics, as will all the other path like environment variables.

I prefer to handle these kinds of requirement locally rather
than globally. For example, here's a bit from one of my session setup scripts which updates CDPATH for *ix semantics.

:: 2009-11-27 SHL Adjust CDPATH to have unix semantics to keep ash happy
if defined CDPATH if "%@substr[%CDPATH,0,2]" != ".;" set CDPATH=.;%CDPATH

See ​http://bugs.ecomstation.nl/view.php?id=3529

set CDPATH=.;..;..\..; (leading .;) works here
