    hm, gcc (as of 4.1.1) doesnt seem to be able to figure that out,
    probably due to the 'nesting + 1' changing the variable.

    Anyway, Arjan's nesting-type idea should solve the problem - in that
    case 'nesting + 1' becomes an identity mapping of a zero-sized variable,
    which will generate zero code.
