Any compiler modern enough to support C99 also supports synthesizing 64-bit integers from whatever the platform makes available.
No, all that C99 requires is support for integers *at least* 64 bits. C99 does not require support for int64_t, i.e., integers that are *exactly* 64 bits.
If we need a type that is at least 64 bits wide, we can use int_fast64_t or int_least64_t. These types are required by C99 and will work even on the rare platforms that lack native 64-bit words. But really, I'm hoping we can avoid the *int*64* stuff. What's the point of putting a 64-bit limit on an API that is supposed to be long-lived and portable?
