With the automounter you end up in the physical path, that you are not
supposed to be using directly [under amd typically /a/machine/dir/blah].
Now, pmake decides to run on a different machine and it remotely asks
for a job to be forked in /a/machine/dir/blah. This might not be currently
mounted in which case you will lose. You need to leave it in, at least if
REMOTE is defined. Feel free to add the above explanation why it is needed.

I am not aware of a shell that does not set PWD.
