Use the explicit template specialization, needed for Tru64 and AIX

2005-04-26  Murray Cumming <murrayc@murrayc.com>

        * sigc++/visit_each.h: Use the explicit template
        specialization, needed for Tru64 and AIX compilers.
        This causes a crash in some uses of sigc::ref()
        (when using g++ 3.3.4 or 3.3.5 , but not with 3.4) but
        seems to fix a crash in some uses of multiple inheritance
        (bug #169225).
        * tests/test_bind.cc: Comment out the crashing (not with
        g++ 3.4) use of sigc::ref() with an explanatory comment.
