No problems, I'd kinda forgotten myself.

I wondered if we could do something like:
BISON_VERSION=`bison -V | head -n 1 | awk '{print $4 }'`
during configure, compare the result to known buggy versions, and take some
sort of action based on that? I haven't delved into configure though, so not
sure how to implement "some sort of action".

I think it is fairly important to try to detect these buggy bisons if the same
problem will be exposed in release versions of the source - it cost me quite
a few hours trying to figure out why make was failing. I'd like to save other
people the hassle (and that list would include people running RedHat Linux
7.3, which includes the bison 1.35).
