Subject: On most other systems "out there", <net/if.h> does not require the
 caller to #include <sys/time.h> first.  I've lost count of the number of
 times I've had to patch this in porting code.  The problem is the "struct
 timeval ifi_lastchange" in the mib stats.  (most other systems don't have
 this, until 4.4bsd anyway).
