	* inf-ptrace.h (struct inf_ptrace_target) <follow_fork>: Likewise.
	* infrun.c (follow_fork): Likewise.
	(follow_fork_inferior): Likewise.
	* linux-nat.c (linux_nat_target::follow_fork): Likewise.
	* linux-nat.h (class linux_nat_target): Likewise.
	* remote.c (class remote_target) <follow_fork>: Likewise.
	(remote_target::follow_fork): Likewise.
	* target-delegates.c: Re-generate.
	* target.c (default_follow_fork): Likewise.
