 Hi, I have been recently working with smart pointers and found out that
 boost ASIO uses std::shared_ptr for void type under Visual Studio 2013
 compiler, what is basically forbidden by standard - void type is an
 incomplete type that can not be complete. It may lead to broken
 compilation under future Microsoft compilers, gcc for sure forbids
 shared_ptr for void type (at least gcc 4.8) throwing static assertion
 during compilation:
 {{{
 static_assert( !is_void<_Tp1>::value, "incomplete type" );
 }}}


 File: asio/details/socket_ops.hpp:63

 {{{
 typedef shared_ptr<void> shared_cancel_token_type;
 }}}
