OK, how about

#if defined(ZSH_64_BIT_TYPE) || defined(LONG_IS_64_BIT)
#ifdef LONG_IS_64_BIT
#define ZLONG_CONST(x)  x ## l
#else
#ifdef ZLONG_IS_LONG_LONG
#define ZLONG_CONST(x)  x ## ll
#else
/*
 * There's some 64-bit type, but we don't know what it is.
 * We'll just cast it and hope the compiler does the right thing.
 */
#define ZLONG_CONST(x) ((zlong)x)
#endif
#else
/* We're stuck with long */
#define ZLONG_CONST(x) (x ## l)
#endif

?  That seems to cover everything we can do within standard C.
