Proposal: shoot vint64 through the head

[Eric S. Raymond]

Today I learned that in C99, "long long" is guaranteed to be at least
64 bits.  POSIX does not guarantee that a 64-bit integral type exists,
only that it is available as int64_t/uint64_t if the platform supports it.

It follows that the combination of C99 and POSIX that we've chosen as
out porting baseline requires int64_t/uint64_t to exist.

There is some fairly nasty code in NTP's calendaring library to work
around the absence of a true 64-bit integral type.  Is it time to rip
that code out?

Or, to put it differently, can anyone think of a compiler/platform
combination we care about that is 32-bit-only?

Data points: GCC and clang both conform to C99 and have 64-bit long long,
whatever the underlying hardware platform.

The ARM ABI requires that "long long" be 64 bits even though the
underlying hardware word length is 32.

and triumph over them."
