1) Include arpa/inet.h for ntohs. 2) Constness fixes. 3) Fix shadowing except for "sin" which shouldn't be in scope. 4) Remove register keyword. 5) Add missing initialsers to user defined structs. 5) Make prototype of netname6 globally visable. 6) Use right macros for printing syncache stats (even though entrie isn't a word).
