Description Johannes Markert 2017-10-21 11:36:18 UTC 
It has already been reported here: https://github.com/westes/flex/issues/265

Adding -D_GNU_SOURCE to CFLAGS solves the problem.

Reproducible: Always

Feels like a dup of bug#628744, and we need a bootstrap snapshot bump here:
Does it work when you set the LATEST_TREE_YES=1 environment variable before (re)starting bootstrap-prefix.sh?

> (re)starting bootstrap-prefix.sh?

Sorry, re-starting won't work, as it won't re-download the snapshot. You'd need to start from scratch with LATEST_TREE_YES=1 set.
Comment 5 Johannes Markert 2017-10-23 09:48:26 UTC 
Setting LATEST_TREE_YES=1 before a fresh bootstrap indeed solved the issue. I didn't know that setting LATEST_TREE_YES=1 in the middle of a run does not have an effect. That's why I issued the bug report.
