Дошло

-      execl("/bin/sh", "sh", "-c", cmd, 0);
+      execl("/bin/sh", "sh", "-c", cmd, (void*) 0);

Указатель и целый могут отличаться по размеру.

Читать документацию.  Если лень искать, то вторая ссылка в G ведёт на
http://www.linuxonly.nl/docs/sentinel/

Так ругается:
execl("/bin/sh", "sh", "-c", cmd, 0);

Так не ругается:
execl("/bin/sh", "sh", "-c", cmd, NULL);
