It needs a test in configure.ac where we check the type, around line
967, to check if LLONG_MIN and LLONG_MAX exist and if so define
ZSH_INT_MIN and ZSH_INT_MAX to those, and a bit later (after
the 64 bit stuff) if we didn't define them yet, test for LONG_MIN and
LONG_MAX and use those, otherwise (which shouldn't really happen) just
use some hackery with sizeof and shifts as a fallback (and perhaps print
a warning that we'd like to know about it).
