--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Not sure if Kai is still active but he contributed push/pop_macro support.

Is there a public specification of the Microsoft extension and how it is
supposed to behave with recursion or is the recursion behavior specified
by the C standard?
