* libio/iofdopen.c (_IO_new_fdopen): Pass _IO_FILE_plus pointer to
_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.
