I'm already using `--gc-sections` flag.
The junk gets into the same section as useful data. In this case 
`--gc-sections` flag doesn't help.
Also `-data-sections` and `-function-sections` doesn't help too.

Wow! Result looks nice. Thanks. But unfortunately `-conf=` flag 
also makes impossible to use the standard library at compile time.

I was also inspired by your `MMIO` library. Great idea! By the 
way, I personally prefer to use `interface` instead of `final 
abstract class`.
