#13467: RTTI issue with non-polymorphic types in debug mode

--------------------------------+---------------------------
 While serializing non-polymorphic types without RTTI in debug mode you get
 compiler warnings and execution crashes. In release mode everything works
 fine.
 This is because dynamic_cast is used for debugging purposes.
 The code is in smart_cast.hpp, starting in line 87:

 {{{
                 #if ! defined(NDEBUG)                               \
                 || defined(__MWERKS__)
                     // do a checked dynamic cast
                     return cross::cast(u);
                 #else

 }}}

 I believe the first line could be replaced with:

 {{{
                 #if (! defined(NDEBUG) && ! defined(BOOST_NO_RTTI) )  \

 }}}

 This solved the issue for me.
