With -funsafe-loop-optimizations we remove them.
Using -Wunsafe-loop-optimizations, we get:
t.c:2: warning: cannot optimize loop, the loop counter may overflow
I mentioned this before to transform the loops such that we know if they
overflow or not and Zdenek
said it was not useful which I feel is still wrong.
