 /* If non-zero, shared library symbols will be added automatically
    when the inferior is created, new libraries are loaded, or when
    attaching to the inferior.  This is almost always what users will
    want to have happen; but for very large programs, the startup time
    will be excessive, and so if this is a problem, the user can clear
    this flag and then add the shared library symbols as needed.  Note
    that there is a potential for confusion, since if the shared
    library symbols are not loaded, commands like "info fun" will *not*
    report all the functions that are actually present.  */
