I already checked in a number of his constification (I keep wanting to
say "constipation" when referring to adding "const" :-)) changes;
they're in the 0.8.1 libpcap.

That's why there's the WPCAP_CONSTIFIED stuff in Ethereal.

0.8.1 doesn't have the change to constify the filter string argument to
"pcap_compile()"; that might require a little more work with
WPCAP_CONSTIFIED if, as I think is the case, WinPcap 3.0 and 3.1 have
the other constifications (it'll have to distinguish between 2.x which
has none of the constifications, 3.0/3.1 which have most of them, and a
future release with the additional one).
