  Add POSIX compat lstat() variant for win32 The existing p_lstat implementation on win32 is not quite POSIX compliant when setting errno to ENOTDIR. This adds an option to make is be compliant so that code (such as checkout) that cares to have separate behavior for ENOTDIR can use it portably. This also contains a couple of other minor cleanups in the posix_w32.c implementations to avoid unnecessary work.
