I am not sure why we need the U postfix in the first place. For literal
like ~0xFFF, the compiler should automatically sign-extends to our
expected size. Personally, I prefer to using ([u]intptr_t) ~0xFFF,
which is more portable. So we don't have to deal with U, UL, i64.
It is possible to use

The U was there for sign-correctness. Without it, gcc complains in a
number of places. I haven't tested it on 64-bit platforms, but on
32-bit intel, it is necessary.
uintptr_t sounds good to me, though; always using pointers seems

Also, the UL[L] should probably be on the inside of the ():
stacklow = '(~0xfffULL)',
I still don't see this one is safer than my proposal.
~((uintptr_t) 0xfff);
Anyway, we should use some kind of macro for this purpose.
#ifndef foo
#define foo(a) ((uintptr_t) (a))
#endif
or

Well, if you ever want to specify a constant longer than 0x7fff, you'd
better put a 'u', 'ul' or 'ull' after
