[Boost-users] [typeof] Duplicate definition of boost::type_of::push_back

Hi,
I'm testing with BOOST_TYPEOF_LIMIT_SIZE greater than 50 and native typeof 
disabled.  I get a "class template has already been defined" error on 
"template<class V, class T> struct push_back" whenever 
BOOST_TYPEOF_LIMIT_SIZE is *not* a multiple of 50.

This is because push_back is defined in both "typeof/vector.hpp" and, for 
example, "typeof/vector50.hpp".  My fix is to change the push_back 
definition in "typeof/vector.hpp" to:

#   if   BOOST_TYPEOF_LIMIT_SIZE < 50
    template<class V, class T> struct push_back {
        typedef V type;
    };
#   endif

Can someone please confirm that this is the correct fix?  A tiny program 
demonstrating the problem is listed below.
Thanks,
Dave Jenkins

#define BOOST_TYPEOF_COMPLIANT
#define BOOST_TYPEOF_LIMIT_SIZE 51
#include <boost/typeof/typeof.hpp>
int main(){
    return 0;
}
