There is no real equivalent, but sometimes there is a workaround.
This depends on the code.

Usually wait3() is used to release dead child processes from their zombie-state.
This can be accomplished in SysV by ignoring SIGCLD :
	signal(SIGCLD, SIG_IGN);
This will prevent the need for waiting for dead child processes.
Just remove all the wait3 stuff.

I used this workaround for porting tinyMUD (the game)
and OLWM (the X11 window manager).
