Update.

1999-01-13  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/syscalls.list: Add __syscall_fork alias.
	* sysdeps/unix/sysv/linux/vfork.c: Use vfork syscall if available,
	otherwise use fork.
	* sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add vfork.
	* sysdeps/unix/sysv/linux/sparc32/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/sparc64/syscalls.list: Likewise.

	* sysdeps/unix/sysv/linux/i386/sysdep.h: Correct handling of
	INLINE_SYSCALL for syscall without parameters.
