        !          1847:        a bit sequence.  DEBUG may only be 0 (no checks or debugging), 1
        !          1848:        (checks, no debugging) or 2 (checks and debugging).  The debugging
        !          1849:        names are parsed by idebug_parse and tidebug_parse in config.c.
        !          1850:        The debugging types are additive.  Many source files changed.
        !          1851:        Inspired by Michael Richardson, Johan Vromans and Peter da Silva.
