I cannot run even standard uBLAS tests right now because my distribution
is stripped of them and I don't have bandwidth to re-download. Neither I
do have any other compiler. There're no problems with the initial test
and, again, with cygwin gcc 3.4.4. The patch can break something:

1) if some other user-defined type is being used (itself not in 'std',
but 'abs' etc for it defined in 'std' as a workaround)

2) if the compiler is outdated (like Microsoft VC6)

Both cases can be true for some people out there. Should there be yet
another conditional macro? (with the default value of?)

I grepped ublas directory a bit, problems can also arise:

1) with 'ZeroElement', 'OneElement' in "ublas/detail/concepts.hpp";

2) (?) with 'vector_scalar_unary_traits', 'vector_scalar_binary_traits'
in "ublas/vector_expression.hpp";

3) with 'std::numeric_limits' when 'BOOST_UBLAS_TYPE_CHECK' is on.

With Best Regards,
