/*
|
|
* vlibc — <stdalign.h>.
|
|
*
|
|
* In C23 alignas and alignof are keywords, so this header defines only the
|
|
* feature-test macros __alignas_is_defined and __alignof_is_defined. In C17
|
|
* (and older) it additionally maps them onto the _Alignas/_Alignof keywords.
|
|
* In C++ the two names are keywords as well.
|
|
*
|
|
* This header is ISO C core and is present in every profile.
