[avr-libc-dev] Hint For Watchdog Disable on Newer AVRs in the Manual

[Harald Kipp]

The manual offers a solution for early watchdog disabling in .init3. 
However, the code uses a global variable to store the current value of 
MCUSR. Isn't this variable cleared again in .init4? Did I miss something?

Anyway, it should be noted, that using .init3 may not work under certain 
circumstances. In our special case the AVR emulates a network controller 
EEPROM, which had to be done before enabling the external memory 
interface. This is done in .init1 and takes too long to reach .init3 in 
time. Any reason why not use __init() to disable the watchdog?

Thanks,

Harald
