I don't know why this happens, but I do have to say that I do that kind
of thing often (in C++ mind you). Q, do you have optimizations on?? That
_might_ to it.
(Certain loop optimizations are somewhat untested, such as
loop-unrolling)

Also, in this case (though w/ gcc it may be somewhat irrelevant) you
could write it as:
for(int x=0;x<=10;x++) printf("%i\n,x).

This makes x local to the loop, and unusable(out of scope) anywhere
else.
