Follow-up Comment #1, bug #54977 (project avr-libc): The data sheet explicitly mentions PCMSK0 for the tiny2313A and tiny4313. There is no mention of PCMSK.
Adding PCMSK0 while leaving PCMSK in place for compatibility with older 2313 code should not cause any issues. In the hopes of getting more attention, I'm attaching a patch to add the missing macro.
