is used. The compiler automatically pads the structures that it
generates, so this manually padded structure still matches the one
generated by the compiler, but if we don't pad manually, -Wpadded
detects that padding is being added and generates annoying warnings.
This hack is necessary as on LLP64 targets sizeof (long) isn't equal
to sizeof (void *). */
