Long bitfields in PODs

[Mark Mitchell]

A type like:

  struct S {
    int i : 8192;
  };

is a POD.

According to 2.4, that means that the underlying C layout rules for
the system should be used.  Unfortunately, that kind of type is not
valid in C.

I believe that all types with bitfields wider than their declared
types should be considered non-PODs for the purposes of layout.

Any objections?
