Is this for LFN=n, or even with LFN calls?  And when you say BUG, do
you mean there's a bug in what our getcwd does, or a bug in Windows?

I think, on balance, returning "d:./" is the best alternative.  It
shouldn't cause too much harm, and in many cases will silently DTRT.
Those cases which fail are no worse than if we return a failure or
some bogus directory.

Indeed.  The Windows 9X issue is an old problem which we live with for
a long time.  I guess setting LFN=n on Windows is not something people
do too often.
