I propose that we at least make "fuller" config (one with more options
set to "yes") work properly:

+               /* Add user to his own group with the first free gid
+                * found in passwd_study.
+                * We try to use --gid, not -g, because "standard" addgroup
+                * has no such short option, it has only long --gid.
+                */
+#if ENABLE_FEATURE_ADDGROUP_LONG_OPTIONS
+               argv[1] = (char*)"--gid";
+#else
                argv[1] = (char*)"-g";
+#endif

If FEATURE_ADDGROUP_LONG_OPTIONS=y, this will work with any "addgroup" -
busybox or standard. If FEATURE_ADDGROUP_LONG_OPTIONS!=y, then user
takes responsibility to ensure that "addgroup" on his system comes from bbox.
