Thanks Paul!

But so far I was unable to reproduce that warning (https://travis-ci.org/akimd/bison/builds/626034753), and if we want to commit avoiding this warning, we should also add it to the set of warnings we check.

Andy, could you please be more specific?  I used several versions of GCC and Clang, and could not get it.  What compiler version were you using, and what platform?

Cheers!
