— macros.h: Add OF_BIGGEST_ALIGNMENT.
When the compiler supports C11, _Alignof(max_align_t) is used; otherwise
the __BIGGEST_ALIGNMENT__ define is tried with a fallback to 16. (user: js, size: 23384) [annotate] [blame] [check-ins using]

on branch trunk
— configure.ac: Fix -Wcast-align check.
There was a warning (resulting in an error) that no root class was
specified, causing the test to fail when it shouldn't, as warnings about
missing root classes were enabled recently. (user: js, size: 23503) [annotate] [blame] [check-ins using]
