Re: [Boost-users] Regression in Boost.Variant with gcc6.3 in C++03 mode

And I believe this finding gives us an easier workaround: Just defining our own `BOOST_IS_CONVERTIBLE` before including `boost/variant.hpp`, and the compilation error should disappear.

``` #include <type_traits> #define BOOST_IS_CONVERTIBLE(T,U) std::is_convertible<T, U>::value

#include <boost/variant.hpp> [...] ```

Oh sorry I forgot you're using C++03. Maybe you could write your own `is_convertible` in C++03 and redirect boost's to there.
