commit 5d29023c110473e13beff16607d85a49673f2b7b
Author: Sebastian Huber <***@embedded-brains.de>

Add __nl_item to <sys/_types.h> and use it

Add __nl_item to <sys/_types.h> for FreeBSD compatibility. Use it in
<langinfo.h> and the Cygwin <nl_types.h>. Make the enum __nl_item in
<langinfo.h> anonymous.
