    Hi!
    The library “LowPower.h” has a problem under compilinge for ATMega168.
    See following link:

    Ralf,

    Seems to be a problem in the 1.6.x branch of the Arduino where the compiler version has been upgraded. It compiles fine on the 1.0.x branch and works accordingly. Let me get into this, probably some changes to the sleep.h file has been made in the AVR library.

    Ralf,

    It seems that extended standby is not supported on the ATmega168. I must have been referring to the avrlibc distribution instead of the datasheet while writing the library. Will do a patch to restrict the usage only to the chips having the extended standby mode support. For now, refrain from using that mode.
