+ variant

wrapper-code have:
char prg_name[MAX_PATH]="/////////////////////";

suid-generator (not have suid, only for root usage) do
copy wrapper-code (not have +x bit to all) to require place and name,
find "////////////////" and replace to "ping\0" (for example),
and set +x +s (and not always for a root).

This method also works for creation suid to the user. :)
