Is this still true in newer GCC releases? Also this was removed in
4.3 and
above.
Yes, on trunk. Searching for dupe before starting a new Bug Report,
came here.
We might close this Bug with a comment on the Prerequisites page
that you
_might_ need bison in the event that you (or a Makefile, broken or
otherwise)
modify a `.y' file.
This webpage does not mention the program bison:
Prerequisites for GCC
http://gcc.gnu.org/install/prerequisites.html
We only require yacc (bison is a yacc) when compiling GCC from the svn
or from the snapshots. Plus most os's already contain a yacc.

I did not modify a `.y' file or play with this part of the code. The
reason
that I require bison is either:
1. I 'hit it' with my configure option combination and found an
untried path.
2. Typing "make distclean" removed a file (I did not see that happen).
3. Something is broken and bison was not really needed.
4. The "Prerequisites for GCC" is incorrect, we do need bison.
