I'm guessing this is a legitimate bug, since the definitions for other registers in the same file (iotnx5.h) otherwise follow convention.

Most AVR headers define the port bits by port name and bit number, as follows (taken from iotn84a.h):
#define PORTB0 0
#define PORTB1 1
These bit definitions match s. 10.3.5 of datasheet.

However, in iotnx5.h, PORTB0 is not defined.  Instead it defines PB0:
#define PB1     1
#define PB0     0

This does NOT match s. 10.4.2 of the datasheet.
