#3084: integer_traits for std::streamsize not defined for Visual C++ in 64-bit
when language extensions are off
----------------------------------+-----------------------------------------
 Reporter:  boost_at_[hidden]  |       Owner:  az_sw_dude 
     Type:  Bugs                  |      Status:  new        
Milestone:  Boost 1.40.0          |   Component:  date_time  
  Version:  Boost 1.39.0          |    Severity:  Showstopper
 Keywords:                        |  
----------------------------------+-----------------------------------------
 The following does not compile if you disable language extensions and
 build in 64-bit:

 {{{
 #include <boost/integer_traits.hpp>
 #include <iostream>

 int main()
 {
   boost::integer_traits<std::streamsize>::const_max;
 }
 }}}

 This makes it impossible to use boost date_time in 64-bit.

 The fix is below (add to integer_traits.hpp):

 {{{
 #if defined(BOOST_HAS_MS_INT64) && !defined(_MSC_EXTENSIONS)
 template<>
 class integer_traits< __int64 >
     : public std::numeric_limits< __int64 >,
       public detail::integer_traits_base< __int64, _I64_MIN     ,
 _I64_MAX>
 { };
 #endif
 }}}
