>Description:
The following is quite annoying, since one often denotes
the meaning of a parameter by its name at the point of
declaration (and documentation):

deal.II/base> cat t.cc
  class X {    X (const int i);  };
  X::X (int) {};
deal.II/base> c++ -W -Wall -c t.cc -o /dev/null
  t.cc: In method `X::X(int)':
  t.cc:1: warning: unused parameter `const int i'
  t.cc: In method `X::X(int)':
  t.cc:1: warning: unused parameter `const int i'

(Yes, the message is repeated twice.)
