[boost] [switch] #include <boost/switch.hpp> gives compiler error under MSVC !

This is very strange given that boost::switch has been dwnloaded from
Vault 1637 times as of now.

But just including

#include <boost/switch.hpp>

Gives a compile error with MSVC 2008 under Vista:

1>boost/switch.hpp(62) : error C2785: 'R
boost::switch_detail::forced_return(boost::remove_reference<T>::type
*)' and 'void boost::switch_detail::forced_return(const void *)' have
different return types
1>        boost/switch.hpp(54) : see declaration of
'boost::switch_detail::forced_return'
1>        boost/switch.hpp(62) : see declaration of
'boost::switch_detail::forced_return'
1>boost/switch.hpp(62) : error C2912: explicit specialization; 'void
boost::switch_detail::forced_return<const void>(const void *)' is not
a specialization of a function template
1>boost/switch.hpp(62) : fatal error C1903: unable to recover from
previous error(s); stopping compilation

I used Linux/gcc till now without problems, but I wonder there is
something wrong in my MSVC setup because I would guess not all the
1637 people that have downloaded switch.zip use gcc.
