These are because of a missing typename. Instead of:

#define PP_CTOR_FORWARDER_PARAM(z, n, _) \
    at_c<VecOfTypes, n>::type BOOST_PP_CAT(a, n) \

It should be:

#define PP_CTOR_FORWARDER_PARAM(z, n, _) \
    typename at_c<VecOfTypes, n>::type BOOST_PP_CAT(a, n) \

> Again, thanks very much!

You're welcome.
