[PATCH][Win] Fix assertion failure when passing 'nul' in input to cc1.

[Rafael Espíndola]

+  #else

+    file_status(file_type Type) : Type(Type) {}

This is never used, right? We always have windows or unix.


While you are at it, would you mind also updating the default constructor?


Do we also crash in some llvm tools like llvm-as? That would allow us
to test directly from llvm.

LGTM with those changes.

Cheers,
