 Thanks to gast128! he found the following bug and reported it in mailing
 lists:

 I get a compilation error with Boost.Variant (which compiles fine on
 previous releases) with vstudio 2010 when a function returns a const
 Boost.Variant, e.g.:
 {{{
 typedef boost::variant<int, double> Variant;

 const Variant GetVar()
 {
   return Variant();
 }


 void TestVariantDnc()
 {
    const Variant var = GetVar();
 }
 }}}
 This gives error C2666 ('boost::variant<T0_,T1>::convert_construct' : 3
 overloads have similar conversions').
