This outputs nothing; setlocale failed.

Haiku lacks locale(1).  config.log shows:
ac_cv_func_setlocale=yes
REPLACE_SETLOCALE='0'

I cloned the current haiku svn tree into something browseable:

http://repo.or.cz/w/haiku.git/blob?f=src/system/libroot/posix/locale/setlocale.cpp

but it's not immediately obvious what locales that supports, nor if it
is newer than the 'alpha 2' release.

I guess that bears asking to the haiku folks.
