Maybe the problem is related to namespace handling in VC 8.0
Boost.numeric.interval library fails when included in uBLAS due to a curious namespace problem.

The same problem effect VC 7.1 as well. Why the compilers think the 'lower' 'upper' symbols are ambiguous I have no idea!
because there are two different ones to choose from
Did I miss the :-) here? If only things were so simple. The error occurs in interval/io.hpp. Here a templated operator definition is being defined in the boost::numeric namespace. The definitions of lower/upper we are looking for are in this same boost::numeric namespace. The definitions which VC is getting confused with in the boost::numeric::ublas namespace can only be found by argument dependant (Konig) lookup. We could look this up in the ISO standard. Circumstantial evidence from several other compilers suggests VC 7.1 / 8.0beta is doing the wrong thing here. Which is why I suspect these compilers do not implement namespace perfectly. Michael
