basic_string comparison

You are looking at it from the wrong angle...

#define lcase(x) (((x >='A') && (x <= 'Z')) ? x-'A' + 'a' : x)
template<class t=char>
class ci_char {
private:
    t m_c;
public:
   ci_char& operator =(t c){m_c = c;}
   bool operator ==(t& c) { return lcase(m_c)==lcase(c); }
   bool operator ==(ci_char& c){ return lcase(m_c)==lcase(c.m_c);}
   ...
};

A couple more operators are needed, of course, but you get the idea. Then you just use ci_char instead of char in std::string... you get case insensitive comparisons, but you also conserve case when copying.
