Synopsis: __attribute__ ((unused) seems misdocumented

State-Changed-From-To: open->analyzed

State-Changed-Why:
    This still applies. I agree that the last sentence of the
    attribute description is un-understandable:
    ---------------
    @cindex @code{unused} attribute.
    @item unused
    This attribute, attached to a function, means that the function is meant
    to be possibly unused.  GCC will not produce a warning for this
    function.  GNU C++ does not currently support this attribute as
    definitions without parameters are valid in C++.
    -----------------
    
    What is the supposed meaning of it? Unfortunately, the CVS
    history does not reach back far enough...
