The problem actually has nothing to do with the macro:
c-forward-decl-or-cast-1 is choking on the const because it's mistaking
it for something that might be part of a member function pointer.
Because c-forward-decl-or-cast-1 fails inside
c-just-after-func-arglist-p, c-guess-basic-offset tries the next best
thing, which happens to be a template argument continuation.

The attached patch resolves the issue.
