 Okay.  Since prstat() uses int64_t (why not uint64_t?), there's no
 point in going with uintmax_t here (for the benefit of PR readers,
 uintmax_t was suggested in tech-userlevel discussion).  So here's
 another patch.  If you want to change the type from uint64_t to
 something else now, there's only one place to change now (the #define
 of BIGVAL).
