freebsd-skq/usr.bin/systat/ip.c
tuexen a04d392ab4 Fix printing of 64-bit counters on 32-bit ppc platforms. 
Several statistic counters are uint64_t values and are printed by systat
using %lu. This results in displaying wrong numbers. Use PRIu64 instead.
While there, print variables of size_t using %zd.
