I have tried some similar changes (put one in a function, etc...) but the
compiler always optimizes it. To be inline is very important due to speed.

The register definitions are in the header files shipped with avr-libc. I will
check them, but AFAIK they are defined volatile. BTW the accesses are
compiled as IN/OUT instructions.
