Hash : aed906e4
Message : This diff is rather large, but it's just simply removing unnecessary headers , remove some lint-style comments, add missing void to functions without args, also some function prototypes (extern) were missing their args, so I added them as they were defined in hack.h OK tb@ on separate diffs
