But don't similar issues arise in Windows ports?

For example, I know that Windows sometimes plays funky games with
letter case in file names.  Suppose the user prefers one case for the
directory name, and sets PWD accordingly.  Won't the user be annoyed if
Emacs uses the different case returned by getcwd?

Similarly, suppose the Windows directory has a mangled file name that
is returned by getcwd, but the user prefers the non-mangled name in
$PWD.

Also, are permissions problems ever an issue on Windows platforms?  In
Unix and GNU/Linux, getcwd can fail because a parent directory is not
readable, and that is an argument for preferring $PWD to getcwd.  Is
such a getcwd failure possible in Windows?
