Why? I'm not much of a C language lawyer, but I would have thought
that in something like
(x) + _a - 1
the "1" will be promoted to the type of the rest of the expression
without any explicit cast. I tested the unsigned long/unsigned int
and u64/int cases of ALIGN(), and my macro with typeof() works for
both of those cases at least.
