Dave,
The only workaround I have is to surround the static assertion with
guards:

#if !defined (__HP_aCC)
 
BOOST_ITERATOR_ADAPTOR_ASSERT_TRAVERSAL(random_access_traversal_tag)
#endif

The assumption is that if "advance" is called, the compiler errors
eventually anyway so this change should be harmless (and lets aC++
compile the code). I had to do the same for "decrement" and
"distance_to" member functions.

Is this workaround okay? I probably should check this in only after 1.32
release in any case.

-Jerry

It should never be instantiated, because it should never be called.
This is a compiler bug.
