Oh, good catch, thanks! Here's a revised patch.

The Unix side of this LGTM.  I have no idea about the Windows
half (... but are we sure GetFileAttributes() can't change errno?)

GetFileAttributes does not set errno. Because it is a Win32 API function rather than a standard C library function, it sets the thread-local Last-Error Code instead.



cheers
