The cctor also fixes a bug that caused a pure virtual function run-time
error with VC when you have the following:
template< size_t n, class C, class CSP >
inline fixed_string< n, C, CSP > runtime_error()
fixed_string< n, C, CSP > res( "oops!" );
return( res ); // pure virtual call here

I'll look into this.
