There is no reason to move it at this point. Certainly it needs to be
part of libc for the forseeable future. Just declare it as COMPAT
in syscalls.master, change the kernel code, and document vfork as
being an obsolete synonym for fork. Then create
libc/compat-43/vfork.c:
------------------------------------
/* This code is in the public domain. */
#include <unistd.h>
int
vfork(void)
{
return fork();
}
------------------------------------
and everything should Just Work. (Make sure to do all of these steps
before recompiling the world, though.)
