+stack.hh(62) : (col. 12) remark: LOOP WAS VECTORIZED.


Thanks for reporting that.  It sounds like you've specified options to
your C++ compiler that make it chatty.  To work around the problem,
you might use different options, which don't cause it to output that
"LOOP WAS VECTORIZED" message.

I've installed the following patch to avoid the problem in future
Bison versions.

2004-02-25  Paul Eggert  <address@hidden>

        * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
        compilers.  This fixes a problem with Intel's C++ compiler being
        chatty, reported by Guido Trentalancia in
        <http://mail.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
