alignment and at most the implementation's alignment limit. This limit is

2**13 on MSVC. To be portable to MSVC through at least version 10.0,

- If 'a' is zero, alignas has no effect.
|
|
- alignas can be used multiple times; the strictest one wins.
|
|
- alignas (TYPE) is equivalent to alignas (alignof (TYPE)).
