* stdint_.h (intmax_t, uintmax_t): Prefer long to long long if both are 64 bits, since this seems to be the tradition, and this prevents gcc -Wformat from warning about usages with PRIuMAX. If we ever run into a host that prefers long long to long in this case, we'll need another configure-time test.
