commit ab90718953eabbd8fa519895387d065c94418f5c
Author: Richard Levitte <levi...@openssl.org>

    VMS: simplify config targets
    
    All VMS config targets were literally copies of each other, only
    differing in what argument the parameter seeking function vms_info()
    received (the pointer size).
    
    This could be hugely simplified by letting vms_info() detect what
    pointer size was desired from the desired config target name instead.
