many unused functions and variables are now commented out You'll still get tons of warnings, which should mostly fall in one of the following categories: 1. Unnecessary variables or values generated from .es scripts 2. Pointers assigned to from functions with side-effects: DO NOT REMOVE! Like CEntity *penNew = CreateEntity_t(...); - even if penNew isn't used, CreateEntity() must be called there!
