_IO_file_attach. 
* libio/iovdprintf.c (_IO_vdprintf): Likewise.
	* sysdeps/generic/strcpy.c (strcpy): Stifle unused-value warnings.
	* sysdeps/unix/sysv/linux/execve.c (__execve): Add const
	qualifiers.  Don't check NULL-terminator of argv & envp.
	* sysdeps/unix/sysv/linux/getsysstats.c (get_proc_path): Use
	unbounded pointer type in word-size assertion.
	* sysdeps/unix/sysv/linux/ptrace.c (ptrace): Add missing
	cases to stifle warnings.
