You should have explained what you think the problem is... But my
crystal ball told me you might mean this:
.L4:
in r24,88-0x20
rjmp .L4
Looks a bit surprising at the first glance, indeed. But only until
you see the source code for it:
while(!(TIFR & TOV0));
TOV0 is number 0. You told the compiler to read TIFR (which it does),
mask all bits out, and then compare it against 0 (the negation). As
masking all bits out is guaranteed to generate value 0, the
comparision will be always true.
I think you meant
while(!(TIFR & (1 << TOV0)));

Never trust an operating system you don't have sources for. ;-)
