/* Determine the alignment of a structure slot (field) of a given type,

Determine the alignment of a structure slot (field) of a given type,
at compile time. Note that the result depends on the ABI.
This is the same as alignof (TYPE) and _Alignof (TYPE), defined in
<stdalign.h> if __alignof_is_defined is 1.
Note: The result cannot be used as a value for an 'enum' constant,
due to bugs in HP-UX 10.20 cc and AIX 3.2.5 xlc. */

Determine the good alignment of an object of the given type at compile time.

For example, with GNU C on x86 platforms: alignof_type(double) = 8, but
