libstdc++/3181: Unable to use sqrt,cos,sin,... with int argument.

[Wolfgang Bangerth]

Benjamin,
3181 is about the following:
  std::sqrt(1)
and 
  int i; std::sqrt(i)
giving overload resolution ambiguities. Since the overloads are only 
provided for floating point types, this is not surprising, so I would say 
that this is actually standards conforming behavior, right? In this case, 
we should close this report.

Regards
  Wolfgang
