I fear that is going to mean that we revert this patch. We are *NOT* moving the minimum bison requirement for this, especially not to a bleeding-edge bison version.
Yes, I didn't mean revert the patch, but I was thinking moving the minimum
bison. But since down to the warning level 3 also resolved the issue,
looks it is a better way to do it.
(On the other hand, if you have an old bison,
you likely also have an old gcc that doesn't know this warning switch, so maybe it'd be all right in practice?)
I just use an old bision and a newer gcc:( and I used "echo "COPT=-Wall -Werror"
> src/Makefile.custom" which is same as our cfbot system. Thank you all for so quick
