commit 5d29023c110473e13beff16607d85a49673f2b7b
Author: Sebastian Huber <sebastian.huber@embedded-brains.de>
Date:   Thu Aug 23 12:13:02 2018 +0200

    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.
