The part-specific include file will be included automatically if:
1) you include "avr/io.h"
2) you properly define the target MCU so that it gets passed to the compiler via the -mmcu option.

Failure to do either of these will result in the register/bit names not being present.

The avr-libc documentation suggests including "util/twi.h".  Why not just follow that advice?  The other twi.h files may be in their respective locations for backward compatibility with previous versions.
