DragonFlyBSD

Hi,

Not sure if I've understood. In the case you pass the "locale" string to setlocale(3):

$ uname -a
DragonFly hammer.df.com 3.6-RELEASE DragonFly v3.6.0-RELEASE #8: Fri Nov 22 13:22:00 PST 2013 root@pkgbox64.dragonflybsd.org:/usr/obj/build/home/justin/src/sys/X86_64_GENERIC x86_64
$ ./t_locale
setlocale(LC_ALL, "es_ES.UTF-8")=es_ES.UTF-8
setlocale(LC_ALL, "en_EN.UTF-8")=(null)
setlocale(LC_ALL, "fake")=(null)
setlocale(LC_ALL, NULL)=es_ES.UTF-8

$ uname -a
DragonFly hammer.df.com 3.7-DEVELOPMENT DragonFly v3.7.1.1227.g566f1-DEVELOPMENT #1: Thu May 22 19:25:43 CEST 2014 root@:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64
$ ./t_locale1
setlocale(LC_ALL, "es_ES.UTF-8")=es_ES.UTF-8
setlocale(LC_ALL, "en_EN.UTF-8")=(null)
setlocale(LC_ALL, "fake")=(null)
setlocale(LC_ALL, NULL)=es_ES.UTF-8

root@testfbsd:/root # uname -a
FreeBSD testfbsd 9.1-RELEASE-p10 FreeBSD 9.1-RELEASE-p10 #0: Sun Jan 12 20:11:23 UTC 2014 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64

setlocale(LC_ALL, "es_ES.UTF-8")=es_ES.UTF-8
setlocale(LC_ALL, "en_EN.UTF-8")=(null)
setlocale(LC_ALL, "fake")=(null)
setlocale(LC_ALL, NULL)=es_ES.UTF-8

In the case of using "" as locale:

DFly:
$ ./t_locale1
setlocale(LC_ALL, "")=(null)
$ echo $LC_ALL
fake

FreBSD 9.1:
root@testfbsd:/root # ./t_locale
setlocale(LC_ALL, "")=(null)
root@testfbsd:/root # echo $LC_ALL
fake

I hope I'm not misunderstanding what you just said.

Best regards,
Antonio Huete

Confirmed as fixed.
