-@c FIXME: Probably should run this through the compiler and get the
-@c whole thing including ".stabs" and so on.
 @example
-f:p13              # @r{where 13 is double}
-f:r12              # @r{where 12 is float}

+In both stabs 3 is the line number where @code{f} is declared

 uses a single @samp{p} symbol descriptor for an argument which is stored
