This is scary.  gcc and clang both parse `void f() { __attribute((aligned)) *x; }` etc. as a declaration; I don't think we want to change that, even if that usage is a bit dubious in modern C.  And it's not clear to me if there are other implications here; does this affect the handling of statement/declaration ambiguity in C++?
