  unless File::Spec->isa('File::Spec::Unix');

Fails on Win32, because File::Spec::Win32 inherits from File::Spec::Unix (see line 11 of File::Spec::Win32 v3.75). Another design issue in File::Spec (in addition to case_tolerant()). File::Spec::Unix is also used as base class for other, unrelated operating systems, instead of using an explicit base class.
