Re: [boost] Re: Why no long long support in integer::int_t?

I believe what I need is a change to boost\integer.hpp along the following
lines

# ifndef BOOST_NO_INT64_T
  template<> struct int_least_helper<?> { typedef int64_t least; };
  template<> struct int_least_helper<?> { typedef uint64_t least; };
# endif

then of course the 5 templates
  template< int Bits >   // bits (including sign) required
  struct int_t
{
...
}

  template< int Bits >   // bits required
  struct uint_t
 {
...
}

  template< long MaxValue >   // maximum value to require support
  struct int_max_value_t
 {
...
}

  template< long MinValue >   // minimum value to require support
  struct int_min_value_t
{
...
}

  template< unsigned long Value >   // maximum value to require support
  struct uint_value_t
{
...
}

will need changing accordingly.

Thanks for the attention,

Stephen
