[avr-gcc-list] Simple question

[Mark Williams (MWP)]

A very basic question... im just having one of those days where i cant see the 
obvious
answer.

I want to do somthing like:

u16 counter=0;

void main(void)
{
        u16 delay;
        while(1)
        {
                if (counter >= delay)
                {
                        //do stuff
                        delay = counter + 1000;
                }
        }
}

INTERRUPT(SIG_OUTPUT_COMPARE2)
{
        counter++;
}

But obviously this wont handle counter overflows too well.  Whats the best way 
to deal with
the overflows, so that the delay still functions properly?  I only want to have 
the counter
increment in the INT as itll be running rather fast, and will chew too much 
processor time
if i start putting compares in there.

Thanks for any tips.
Mark.
