Yes, that helps. But that raises another question; should WinPcap/libpcap
users really have to remember to set '-D_USE_32BIT_TIME_T'? If so, what a kludge!
Maybe there should be a new 'struct npf_sys_timeval' structure to match
what npf.sys was built with. Or a runtime check to warn users bout this?
What do you say Gianluca?
