tempd failure on MSWin32

as seen in http://www.cpantesters.org/cpan/report/6aa5d161-6bff-1014-b852-a17c890cd912

File::pushd::tempd returned "C:\perl\cpan\build\MooseX-Types-Path-Tiny-0.010-nLTVPJ/\tmp\6X2WD92VsI", which isn't a valid path. (Note the two path separators before 'tmp').

Here's another, slightly different, case: http://www.cpantesters.org/cpan/report/96c89ed8-6c09-1014-bbd2-84909b19dd04

Can't chdir to C:\perl\cpan\build\MooseX-Types-Path-Tiny-0.011-xyimHA/C:\Users\a00772a\AppData\Local\Temp\_JRIO94omK: No such file or directory at t/arrayref.t line 24. at t/arrayref.t line 24.

It looks like pushd() is getting confused about whether the dir is already absolute.
