The code is new in 1.2.1, and identical code in Rcmd clean works. It looks
like a Windows Perl bug.  On my machines under NT4 and 98 this works
because -d foo seems to be always true!  It is probably different on 2000.

Try changing the line

        unless (-d $TMPDIR);

to
        unless (-e $tmpdir);

It may also depend on the Perl version.  We know that system() is broken
in builds later than ca 619, for example.

It's strange that after years of problems with the make and shell, Perl
is now misbehaving.
