            Bug ID: 58412
           Summary: C++11 : numeric_limits::stuff must be constexpr
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

Hello,
numeric_limits::stuff must be constexpr, as required by the C++11 standard
see the C++11 section in
http://www.cplusplus.com/reference/limits/numeric_limits/

Such behaviour is required to use this values as static const variables, or as
default variables for functions.

e.g.

struct A{
    static constexpr double NaN=std::numeric_limits<double>::quiet_NaN;
    f(double d=NaN){};
};
