FIX: C4114 Warning When Using Templates and Const Keyword (138752)

CAUSE

The compiler incorrectly expands the type of the function parameter to const T as it expands a template with type const T when the definition of a function or member function template has a parameter that takes a const T.

The Help file gives the following information for C4114:

• Same type qualifier used more than once.
• A type qualifier (const, volatile, signed, or unsigned) was used more than once in the same type declaration or definition. The second occurrence of the qualifier was ignored. This is a warning when Microsoft extensions are enabled (/Ze) and an error when extensions are disabled (/Za).
• The following is an example of this warning:

     volatile volatile int i;   // warning

   // test.cpp
   // Compile options needed - none
   template <class T>
   struct f
   {
     void goo( const T & r){ T t=r;};
   };

   void main()
   {
       f<const int> h;

       // the following line of code causes
       // goo( const const int ) to be expanded
       h.goo( 2 );
   }
