Fixes former crash in drawline16 and swaps drawpixel with the unsafe variant there; fixes potential sector[-1] access in sliding Star Trek doors; make CC overridable in Makefiles so that other toolchains or static analyzers like scan-build/clang can be used; with its help, fix some issues, some more severe than others.
