ATtiny compile fail: 'TIMER2_COMPA_vect' appears to be a misspelled signal handler

[pediRAM]

Try to compile following code for an ATtiny 84A:

#define PIN_MOTD_IN 0
#define PIN_LED_OUT 1

int val = 0;

void setup()
{
    pinMode(PIN_MOTD_IN, INPUT);
    pinMode(PIN_LED_OUT, OUTPUT);
    digitalWrite(PIN_LED_OUT, LOW);
}

void loop() 
{
    val = digitalRead(PIN_MOTD_IN);
    digitalWrite(PIN_LED_OUT, val);    
    delay(50);
}

and you will get following warning:

rdware\avr\1.6.10\cores\arduino\Tone.cpp:37:0:

Attiny chips can be used with external cores like

The only Arduino product based on these chips is the Gemma who has a tiny 85

Some comments on these issues:

ATtiny Compile Fail: Redefinition of preproc. symbol "BIN" (from "Stream.h" and "Print.h") by "iotnx4.h" #4784

-> Fix it in Print.h

• Either define an enum in print.h for DEC,BIN,OCT,HEXA
• Or rename them to DEC_NUMBER, BIN_NUMBER, etc. or DECIMAL, BINARY OCTAL etc.
• Or replace DEC by 10, and skip the define altogether (it's overkill anyways)
  Only DEC is used, and has to be updated in 2 files.

You can also hack it by removing BIN from print.h without any adverse effect. It's not used.
