The symbol to define to 1 if a pointer to an int fits in a long is
...
INTPTR_IS_LONG, not INTPTR_IS_ULONG -- the latter is unused in
other parts of lint's code. This stops vax's lint from complaining
about conversion of integer constants to 'unsigned long' in function
argument lists, via a proper define of INT_RSIZE in common/inittyp.c.
sh3 defined this to 0, so was actually not affected, but better to
eradicate the typo there as well.

Make a minimal attempt at distinguishing between the hosts and the
...
targets integer data type value ranges. For now we just use the
hosts uint64_t for parsing & storing integers constants, and test
against the targets limits and assign appropriately, instead of
sometimes (inappropriately) going via the hosts u_long type. As
long as none of our architectures have target long or quad data
types strictly larger than 64 bits, we should be fine with this
fix.
Furthermore, as they stand at the moment, we can't use the current
TARG_INT_MAX and TARG_LONG_MAX constants in C preprocessor expressions,
so remove the conditional on them being equal. Yes, this will
produce dead code for some targets.
This allows an ilp32 host to lint for an lp64 target which uses
e.g. the targets ULONG_MAX constant without triggering an "integer
constant out of range" warning.
OK'ed by christos.
