newlib/winsup/utils/mkpasswd.c
Corinna Vinschen 9ae2974ffd * mkpasswd.c: make default home directory /home/$user if one 
can't be found in user registry. Allow user to override
        that with command line arg.
        (longopts): Fix typo in `local-groups' option.
        (main): Initialize `passed_home_path' before first usage.
