8.1 alignof and alignas

Gnulib module: alignasof

The alignasof module arranges for alignas and alignof to be more like standard C.

Portability problems fixed by Gnulib:

• Pre-C11 platforms lack alignas and alignof.
• On pre-C23 platforms, <stdalign.h> must be included before using alignas or alignof. See stdalign.h.

Portability problems not fixed by Gnulib:

• On pre-C23 platforms, alignas and alignof are macros.
