patch: two little warnings

[Werner Almesberger]

This patch fixes one missing prototype I must have overlooked, and it
properly hides sccsid in libc/misc/unctrl.c and libc/sys/sysvi386/crt0.c

---------------------------------- ChangeLog ----------------------------------

2000-08-28  Werner Almesberger  <Werner.Almesberger@epfl.ch>
	* libc/posix/execve.c: included unistd.h for "_execve" prototype
	* libc/misc/unctrl.c libc/sys/sysvi386/crt0.c (sccsid): changed
	"#ifndef lint" to "#if defined(LIBC_SCCS) && !defined(lint)" like
	everywhere else
