-It was once true that, when installing Bison on Sequent (or Pyramid?)
-systems, you had to be in the Berkeley universe. This may no longer
-be true; we have no way to tell.
+Bison requires GNU m4 1.4.3 or later. See:
-On VMS, you will probably have to create Makefile from Makefile.in by
-hand. Remember to do `SET COMMAND BISON' to install the data in
-`BISON.CLD'.

-VMS and MS-DOS builds are probably broken right now. If you are able
-to build Bison on either platform and you need to make changes to do
-so, please submit those changes as a bug report.
+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.
-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.
