gengtype doesn't understand about struct-scope for typedefs, and
consequently gets confused if multiple classes define the same-named
typedef. The regular default_hash_traits is invisible to gengtype, so
it doesn't barf on the first specialization, only on the second -- which
is what I'll be adding soon.
This patch tells gengtype to move along, nothing to see here.
Applied as obvious.
