Remove old false positive avoidance code

From email explaining existence in the first place:

    This is from before when the used checks throwing false
    positives about unused due to changing the definition without
    checking whether it *had* a value to begin with and me not
    realizing they were false positives. I was thinking that it was
    warning from ARGC et. al. not being used since the previous
    macro or function call and the new value warning about
    overwriting the old value.
