Issues with constant expression

I have some issues in compiling a code. I have this particular code

    typedef double Type;

    static const Type MAX_VALUE = __DBL_MAX__;
    static const Type MIN_VALUE = -__DBL_MAX__;

Now when I try to compile it. It shows the following error 

error: a call to a constructor cannot appear in a constant-expression

I change the definition const to constexpr. But it shows the following error

error: ‘constexpr’ does not name a type
note: C++0x ‘constexpr’ only available with -std=c++0x or -std=gnu++0x

How can I fix this issue?

My crystal ball tells me these lines are inside a class definition. That's a very important piece of information you left out.

Prior to C++11, only integral and enumerated static members could be initialized inside the class body. Others, including floating-point, must be defined outside.
