caan any body cross check my logic in c programming

hi friends,my project is a temperature sensor device controlled by Atmel tiny here is the c program.I have checked this program on AVR simulator and its working fine on simulator,i have adevelopment board of olimex when i tested this program and made the led to blink its continously blinking for ever,i mean its haing a watchdog timer function for a period of about 2 minutes,as far this function led should blink for 2 mins and then reset should occur
