* mkgroup.c (load_netapi): New function to load netapi32.dll functions

Browse Source 
dynamically so that mkgroup works on 9x/ME as well.
        Use corresponding function pointers throughout.
        (usage): Change to `int'. Change text to be conformant to mkpasswd.
        (main): Use `getlongopt' to process options.
        Special handling to create a group entry on 9x/ME.
