+Bison can work with pre-1.4.3 distributions of GNU m4 if they are
+sufficiently patched, but if you encounter a bug with an older
+distribution and report a bug we will probably suggest that you
+upgrade to 1.4.3 as the first step in trying to fix it.
+
+Please send bug reports to <bug-bison@gnu.org>. Please include the
+version number from `bison --version', and a complete, self-contained
+test case in each bug report.
+
+If you have questions about using Bison and the documentation does
+not answer them, please send mail to <help-bison@gnu.org>.
