PC-Lint reports errors for VC6-specific implementation in is_same.hpp

11 Aug 2003

      Hi all,

Since I have included boost\dynamic_bitset.hpp in my project,
PC-Lint reports many thousands of redefinitions of symbol
'is_same_part_1<<1>>::part_2<<1>> for the following code 
in type_traits\is_same.hpp.

#ifdef BOOST_MSVC
// the following VC6 specific implementation is *NOT* legal
// C++, but has the advantage that it works for incomplete
// types.

template< typename T1 >
struct is_same_part_1
{
    template<typename T2>  struct part_2     { enum { value = 
false }; };
    template<>             struct part_2<T1> { enum { value = 
true }; };
};

If I replace

    #ifdef BOOST_MSVC

with

    #if (defined BOOST_MSVC) && (BOOST_MSVC < 1300) 

The code compiles with Visual Studio .NET 2003 and PC-Lint doesn't
report any error.
