FWIW, the como -E compile command produces this output:
<-----------------
namespace boost { namespace mpl {
template<
      typename C = na
    , typename F1 = na
    , typename F2 = na
    >
struct eval_if
: if_<C,F1,F2>::type
{
};
...
...
-----------------
That's probably not the problem, because with this input:

<-------------
#include <boost/mpl/eval_if.hpp>
struct A{};
struct B{};
struct C{};
typedef boost::mpl::eval_if<A,B,C>::type X;
X x;
...
-------------
compilation succeeds.
