I wasn't aware of any strong dependency such as this one (and I actually still have not understood what the problem is, and how problems with AC_SUBST are related to Bison here). The only I see in gnulib which is a *.y is lib/parse-datetime.y. And I don't see anything special in it that would require any special version of Bison. Just in case: $ for i in /usr/local/stow/bison-3.* do echo "$i..." $i/bin/bison lib/parse-datetime.y done /usr/local/stow/bison-3.0.5... /usr/local/stow/bison-3.1... /usr/local/stow/bison-3.2.4... /usr/local/stow/bison-3.3.2... /usr/local/stow/bison-3.4.2... /usr/local/stow/bison-3.5.4... /usr/local/stow/bison-3.6.4... /usr/local/stow/bison-3.7... /usr/local/stow/bison-3.7.1... /usr/local/stow/bison-3.7.2... /usr/local/stow/bison-3.7.3... I think I have not understood the question, sorry :( What exactly happens here? Is configure properly rerun each time, without cache? Why are we talking about Bison?
