So for a struct, aligning the first field of it is effectively aligning the
struct.
But that seems a variable attribute rather than type attribute, a very
different usage. (as is documented here
https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html#Common-Variable-Attributes).
And for
typedef int more_aligned_int __attribute__ ((aligned (8)));
it's still an issue.
