Folks,

    I found an old thread (<http://lists.boost.org/MailArchives/ublas/ 
2005/10/>) about suppressing warnings about "unused variables".   
Similar warnings occur in matrix.hpp which it seems have never been  
fixed.  Here is a patch (two lines added) for matrix.hpp along  
identical lines to what has been done for vector.hpp.  The patch is  
against Boost version 1.33.1 (although the latest CVS release of  
matrix.hpp also does not have the changes, as far as I can tell).   
Cheers,

                                              --Jordan
