John Maddock reported and explained this problem to me some time ago
(thanks!) and I've (hopefully) implemented a *ugly* workaround for it. The
problem is due to the questions of DR 135 and its (new ;-) interpretation
through MS. The correct solution probably would be to separate class member
declarations and definitions, but then the code probably wouldn't work with
MSVC 6.0 anymore :-(.

You can download one of the newer version from
http://groups.yahoo.com/group/ublas-dev/files and try to enable

// #define BOOST_UBLAS_NO_NESTED_CLASS_RELATION

in the MSVC section of ublas' config.hpp. But be aware that you're probably
one of the first to give this a try ;-)
