I think I see why the compiler is complaining here. There are two copy
constructors defined in <blitz/vector.h> for the class template Vector
(for const and non-const reference arg), when really only one is
required. If we just eliminate the version with the non-const argument,
the warnings should go away. Try removing or commenting out lines
100-105 in <blitz/vector.h>, and let me know if this resolves the problem.

Could you please elaborate here? What problems are you referring to?

Yes and no. I check into cvs bug fixes as issues are reported and
resolved. I also periodically generate a new tarball if there are lots
of bug fixes since the previous release or I have done some significant
code modifications. The schedule is irregular, as I have the spare time
to work on this or as volunteers offer to help me.
