Describe the problem you're observing

make distcheck is failing on Travis for one of my pull requests. When I tried it in the vanilla dev branch, it failed for me too:

$ make distcheck

...

I'm guessing it's related to needing --with-gotcha=... at the configure step.

Describe how to reproduce the problem
