I just posted version 1.5. From the notes:
Version 1.5 Thu Feb 2 18:09:49 CST 2012
Added the PCintPort::pinState static variable to allow the programmer to query the state
of the pin at the time of interrupt.
Added two new #defines, NO_PIN_STATE and NO_PIN_NUMBER so as to reduce the code
size by 20-50 bytes,and to speed up the interrupt routine slightly by declaring that you
don't care if the static variables PCintPort::pinState and/or PCintPort::arduinoPin are set
and made available to your interrupt routine.
// #define NO_PIN_STATE // to indicate that you don't need the pinState
// #define NO_PIN_NUMBER // to indicate that you don't need the arduinoPin
