[boost] Re: ublas and VC++7.

I just ran into this as well.  The problem seems to be
related 
to MSVC's new strictness with the typename keyword,
which doesn't interact well with forward declarations
and nested classes.
 
I was able to get it to work by adding the line
 
   typename self_type::
 
just before the return value of every function that caused
the problem, e.g. in matrix.hpp line 404:

            BOOST_UBLAS_INLINE
               typename self_type::
            const_iterator2 begin () const {
                const self_type &m = (*this) ();
                return m.find_first2 (1, index1 (), 0); 
            }

 
There are 60 places that needs to be done, but they're all identical.
 
I don't know how good a fix that really is, and for all I
know it may break other compilers (including VC7.0).
But it ought at least let you get on with what you're doing,
until a new release (compiler or library) that fixes
the problem for real.
 
Hope it helps---
