// macro	stat_size_join_sep
//
// purpose      Return size of a file where the file name is given as multiple
//		string arguments to be joined together with a directory
//		separator between each argument.
//
// arguments	1..N (const char *) file name parts
//
// returns	(long long) == -1 : [failure, see errno]
//		(long long) >=  0 : [success] file size
//
// note		A (long long) type is returned so that if type (off_t) is a
//		smaller unsigned integer, it's full range of values will not
//		collide with the error return value.
