Finally I found out that aCC has a problem with the typename mixed with the 
template spec. So if I write the construct like this it works. Could you 
apply this patch ?

struct if_
{
  typedef if_c<
          BOOST_MPL_AUX_ICE_CAST(bool, BOOST_MPL_AUX_VALUE_WKND(C)::value)
        , T1
        , T2
        > parent_type ;
  typedef typename parent_type::type type;

    BOOST_MPL_AUX_LAMBDA_SUPPORT(3,if_,(C,T1,T2))
};
