[avr-gcc-list] PORTC

[Andi]

Hi,     I have a program for atmega8 and the program is working well when I compile it using WinAVR-20040404-bin-install.exe. But when I compile it using

WinAVR-20071221-install.exe  the program isn't working anymore. And I found something, the compiler didn't the code to set and clear PORTC. I had tried using PORTC |= (1<<n) and PORTC &= ~(1<<n) but still the compiler won't compile it.   Is it a bug ? Or , do I miss something ?     Andi
