The ANSI C way would be:
#include <machine/_inttypes.h>
int64_t i;
printf("%"PRId64"\n", i);
It's probably bad form to directly #include a file name with an
underscore into an implementation file, but I don't see any other way.
Maybe we could create a <sys/inttypes.h> that #includes the necessary
files to be a kernel equivalent of <inttypes.h>.
