The issue is not really that of __alignof__(double) not being an
integral constant -- surely it is.  Try to use it in contexts where
the Standard requires an integral constant expression.

The real issue is having to do with __aligned__.

Try

   struct A {
     enum { constant = 4 };
     __attribute__((__aligned__(constant))) char data;
   };
