branch: master
commit 6ef14349fa73922473ba8202e256f20e17661b25
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>
Don't require GNU putenv
* configure.ac: Use system putenv even if it lacks GNU features, as
we don't need them. This works around a bug in FreeBSD 10.1 getenv.
Fixes: bug#19874
