#if in compilation for use or arduino UNO and ATMEGA 328 or LILY with ATTINY 85

pfff ... I am such a dummy sometime ... my code was false :

#if defined TARGET_ARDUINO
    GIMSK = 0b00100000;    // PCIE on
    PCMSK = 0b00000011;    // mask pour le pcint0 et pcint1
#endif
#if defined TARGET_ARDUINO
    PCICR = 0x02;          // Enable PCINT1 interrupt
    PCMSK1 = 0b00000111;
#endif

if I use twice ARDUINO there is nothing for LILY ....

thanks for your help, sorry to have had you loose your time !!
