* It is intentional that the condition for natstr is HAVE_TRUE_LONG_LONG
* instead of HAVE_LONG_LONG or LONG_LONG.
* This means q! and Q! means always the standard long long type and
* causes ArgumentError for platforms which has no long long type,
* even if the platform has an implementation specific 64bit type.
* This behavior is consistent with the document of pack/unpack.
