    # to know how to interpret them according to their real type,

    # being told they are ints or functions returning int like old
    # versions of gdb used to do.

    # out debugging info for non-aggregate return values of functions
    # even without -g, which should be accepted.

    # encapsulates ecoff debugging info in a .mdebug section.
    # Irix6 gcc omits no debug info at all for static functions and
    # variables, so all tests involving statics fail.
