95The PATHEXT env variable will be used to get a list of extensions that

474dmake can handle Unix style cd'ing but nmake (at least 1.5) cannot. It
475wants:

478 command
479 another_command
480 cd ..
481
482B<NOTE> This cd can only go one level down. So far this sufficient for
483what MakeMaker needs.
