No, it doesn't require that. It requires macros PRId64 and friends to 
exist, iff the compiler claims C99 conformance and has an int64_t.  But 
that's about it.

The __PRI64_PREFIX you used is just an implementation detail of whatever 
libc you looked at.  Those two leading underscores (followed by anything 
else but "STD") are pretty much a dead giveaway.  As should be the fact 
that this macro does not actually appear in any of the documentation ;-)
