That is a different scenario. In this new scenario, you first use a
POSIX shell to set a preferred name with PWD. You then use a
non-POSIX shell to change the working directory to a different name
for the same directory, without also setting PWD.
Yes, in this case, Emacs will use PWD rather than the name you
specified to the non-POSIX shell. But this also happens on Unix
platforms with non-POSIX shells. It is not a problem that is specific
to Windows. And once we fix the bug in w32.c it will not be that
serious a problem, since Windows Emacs will act like GNU/Linux or Unix
Emacs in this situation.

Some do, but most don't. For example, GNU 'tar' doesn't, even though
it uses getcwd (in order to implement the -C option).

On Solaris 8, the standard shell program /bin/sh is not a POSIX shell,
and it does not set PWD. The situations are analogous. I still don't
see why Windows should be treated differently.
