I am building a project for an ATtiny2313. I have just noticed that the signal name for the external interrupts are SIG_INTx instead of SIG_INTERRUPTx that is used for other devices I use and which is included as the signal name for external interrupts in libc documentation.
What I suggest is to define both signal names in the device header or a note to the documentation (even better a seperate table of signal names for each device).
This is just a suggestion, but I would like to see an answer for this.
Keep on the great work you are doing guys.
