[Boost-users] [variant] recursive_variant_ broken with VC++ 2005 SP1

Hello,

Using 1.34.0 and 1.34.1 RC, this used to work with 2005 but with SP1
it is now broken:

boost::make_recursive_variant<
   int,
   std::pair<int, boost::recursive_variant_>
>::type foo;

It now gives the error:

utility(54) : error C2079: 'std::pair<_Ty1,_Ty2>::second' uses
undefined struct 'boost::recursive_variant_'
        with
        [
            _Ty1=int,
            _Ty2=boost::recursive_variant_
        ]

I was able to fix this by #defining
BOOST_VARIANT_NO_FULL_RECURSIVE_VARIANT_SUPPORT before including
variant.hpp.
