Great.  Using "%lld" to print an int64_t value still isn't portable.

It's guaranteed to be at least 64 bits.  I've never heard of a system
where it's more than 64 bits.  If there's a tradeoff between convenience
and portability, you'll have to decide how to resolve it.

It's at least 32 bits; 32 and 64 are both common.

C requires int to be at least 16 bits.  POSIX requires it to be at least
32 (Win32 probably does too).

Yes, it pretty much does, if you use it properly.  (No doubt supercat
will jump in and repeat his earlier remarks about not knowing which
intN_t types are promoted to int in expressions.)

If you want to call printf from some non-C language, the calling code
will have to have some awareness of the characteristics of the relevant
types as used by the C compiler that compiled the printf implementation.
If your foreign code uses a "%lld" format, it will have to figure out
how to pass something equivalent to a long long int argument.  It will
also have to deal with the parameter passing convention for variadic
functions if it differs from non-variadic functions.  If there's an ABI
for the platform it might provide some guidance.  I can think of ways to
approach the problem, but I won't go into detail without some concrete
information.

printf() is a standard C function, designed to be called from C code
compiled with a C compiler.  Calling it from another language is going
to be difficult.  If you want to ask how to do that, we'll need more
information than you've given us so far.  (You might consider setting up
some C wrappers.)
