...and changes a data structure exported by libpcap (it adds stuff to  
the end of the structure, so it *might* not completely break binary  
compatibility, but...) *and* doesn't handle the case when you read  
from a savefile (no, you can't add that information to the savefile  
unless you do it with a new magic number - which would mean that  
existing tcpdumps couldn't read the new files).
