A flash of light this morning suggested adding the following lines to cores\tiny\pins_arduino.h
// Pinched from https://raw.github.com/mharizanov/TinySensor/master/NewSoftSerial_Attiny84/NewSoftSerial.cpp
#elif defined(__AVR_ATtiny84__)
#define digitalPinToPCICR(p) (((p) >= 0 && (p) <= 10) ? (&GIMSK) : ((uint8_t *)NULL))
#define digitalPinToPCICRbit(p) (((p) <= 2) ? 5 : 4)
#define digitalPinToPCMSK(p) (((p) <= 2) ? (&PCMSK1) : (((p) <= 10) ? (&PCMSK0) : ((uint8_t *)NULL)))
#define digitalPinToPCMSKbit(p) (((p) <= 2) ? (p) : (((p) - 10) * -1))
