* NEWS: %expect-violations are now just warnings, reverting
to Bison 1.30 and 1.75 behavior.  This fixes the GCC 3.2
bootstrapping problem reported by Matthias Klose; see
<http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
* src/conflicts.c (conflicts_print): Likewise.
* tests/conflicts.at (%expect not enough, %expect too much,
%expect with reduce conflicts): Likewise.
* doc/bison.texinfo (Expect Decl): Document this.  Also mention
that the warning is enabled if the number of conflicts changes
(not necessarily increases).
