No that is not is being warned about. The statement that is being warned about
is just "i;" which is the same inside a for statement as it is outside one.
Both are statements have no effect as it does nothing.
Take:
void f(int i)
{
i;
}
Do you think that should be warned about? That is the exact same thing which
is being warned about when you have:
void f(int i)
{
for(i; .... ; ....)
....
}
