Ticket 49364 - incorrect function declaration.
    
    Bug Description:  The pbkdf2 calculate iterations function had a missing
    argument in the header definition. This would not affect 64bit platforms
    but did affect 32bit environments because of the way that uint64_t is
    structured on these platforms.
    
    Fix Description:  Correct the header definition to include the time
    argument.
