Details:

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.

Status: None => Confirmed
Release: 1.8.0 => 2.0.0

Follow-up Comment #1:

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