 Wouldn't return Arg1 == Arg2 ||
 std::toupper<T1>(Arg1,m_Loc)==std::toupper<T2>(Arg2,m_Loc);
 be faster, since it might avoid the toupper calls?

 {{{
             template< typename T1, typename T2 >
                 bool operator()( const T1& Arg1, const T2& Arg2 ) const
             {
                 #if defined(__BORLANDC__) && (__BORLANDC__ >= 0x560) &&
 (__BORLANDC__ <= 0x564) && !defined(_USE_OLD_RW_STL)
                     return std::toupper(Arg1)==std::toupper(Arg2);
                 #else
                     return
 std::toupper<T1>(Arg1,m_Loc)==std::toupper<T2>(Arg2,m_Loc);
                 #endif
             }
