[Click] directiplookup.hh

[Bob Keyes]

Um, well, I seemed to have got over my previous problem by simply
switching to cvs code. But now another problem shows up, both for my
native (x86) environment and the cross-compilation.

g++ -W -Wall -fno-exceptions -fno-rtti  -DHAVE_CONFIG_H -I../include
-I../include -I. -I..  -DCLICK_USERLEVEL -g -O2 -MD -c
../elements/ip/directiplookup.cc

This is with gcc 3.3.5, with click configured with the roofnet suggested
config.
