    From the standard - 6.7.3 6 "An object that has volatile-qualified type may be modified in ways unknown to the implementation or have other unknown side effects. [...] What constitutes an access to an object that has volatile-qualified type is implementation-defined."

    This mostly indicates the compiler to avoid any optimisation on that variable.
    Using const with it is fine.
