- Fixed GS_PIERCINGSHOT, it should ignore defense
- Corrected Gatling Fever costing SP when trying to turn it off. Also, speed increases bonuses won't take effect while it's active.
- Updated the main makefile with a new OPT line. It is commented by default since it only works with GCC 4.X, when unset, it will hide away a huge amount of warnings that have to do with stuff that is not gonna be corrected in eA anyway.
