Umm, what? That sounds entirely counterintuitive to me.

If the global integer is non-static, it could be referred to by another 
object file, so the compiler cannot omit it from the generated object 
file. On the other side, if the variable is static, the compiler has full 
visibility over any possible use, and sees that nothing in the same object 
file refers to it, and thus can omit it if it's unused.
