It is defined in 2.4.20, undefined but reserved:

werewolf:/usr/src/linux-2.4.20> grep -r exit_group *
arch/x86_64/ia32/ia32entry.S:   .quad sys_ni_syscall    /* exit_group */
arch/i386/kernel/entry.S:       .long SYMBOL_NAME(sys_ni_syscall)       /* sys_exit_group */
include/asm-x86_64/ia32_unistd.h:#define __NR_ia32_exit_group           252
