_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. * libio/iofdopen.c (_IO_new_fdopen): Pass _IO_FILE_plus pointer to _IO_file_attach. * libio/iovdprintf.c (_IO_vdprintf): Likewise.
