Well, now it compiles with -O2 too.

But I've got another problem.

My keyborad IRQ0 ISR puts 1 to an array, if a key is pressed and puts 0, if it
is released.

But with optimizations enabled, I simply get faulty code, since compiler
eliminates checking of the array. How to prevent this from optimizations?

thanks.
