Re: Error-out on compiling current CVS: preproc

Folks,

Update on this:  Just tried it with:
SuSE 9.1, GCC 3.3.3, Bison 1.875
and don't get the error.

So it looks like the requirement for Bison 1.85+ is now a "hard" requirement?  
We'll need to document this, since SuSE 9.0 is less than a year old, and I'm 
sure some other distros are still using 1.75.

I see in configure.in:
AC_CHECK_PROGS(YACC, ['bison -y'])if test "$YACC"; then  if $YACC --version | sed q | $AWK '{ if ($4 < 1.875) exit 0;
elseexit 1;}'; then    AC_MSG_WARN([*** If you are going to modify the grammar files or build from CVS, the
installed***version of Bison is too old.  Bison version 1.875 or later is required.])  fifi
 

Looks documented to me.

Aha.  Yeah, blew past me too fast to read.  Hmmm ... does that mean that this 
error won't happen in the release version?

I think so. The only reason you need bison in the release version is if
you modify the grammar files.

You shoouldn't need bison at all with a release tarball -- the 
preprocessed grammar file is distributed with it.

Also, installation.sgml specifically says 1.875 or newer, and the 7.4
release notes already said 1.85 is required.  I don't know where else
we would document it?
