Would you rather I change pax so that:
   	a) it uses unsigned long long instead of u_longlong_t, or
   	b) fix the port with the uncommon definition for u_long_long ?


(b) isn't valid, from <sys/types.h>:

	typedef quad_t          longlong_t;     /* ANSI long long type */
	typedef u_quad_t        u_longlong_t;   /* ANSI unsigned long long type */

it could be
	
	b) fix the definitions of *longlong_t.

though :-)
