One is the normal way, where I just compile it file by file like everyone else. The other way is this cheesy "#include everything" trick. It lets the compiler make better decisions about what to inline and things of that nature. Perhaps the compiler can also relocate functions better (not sure). At any rate it makes for faster binaries. On the other hand, you have to make sure that all your header files are idempotent.
