We should have them so that not every .c file needs to include all of the stuff which this file need for building. This way we can remove some headers from other files and get better picture what is needed. This can save some compilation time. And this can help if we sometimes want to separate this one big header. Also use forward declarations for structs and enums when it not included straight with include and it is used in function declarations input. This will prevent possible compiler warning: xxx declared inside parameter list will not be visible outside of this definition or declaration Here is list which I made when parsing this.
