	+The
	+.Fn static_assert
	+macro expands to
	+.Fn _Static_assert ,
	+and contrarily to
	+.Fn assert ,
	+makes assertions at compile-time.
	+Once the constraint is violated, the compiler produces a diagnostic
	+message including the string literal message, if provided.
	+The initial form of the
	+.Fn _Static_assert
	+containing a string literal message was introduced in C11 standard, and
	+the other form with no string literal is to be implemented by C2x and
	+some compiler may lack its adoption at present.
