    # able to interact with these variables with some care (they have

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

    # since gdb doesn't know the type), but (b) users should be able

    # to detect that gdb does not know the type, rather than just

    # being told they are ints or functions returning int like old

    # versions of gdb used to do.

    # On alpha (and other ecoff systems) the native compilers put

    # 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 emits no debug info at all for static functions and

    # variables, so all tests involving statics fail.
