(headers): Add sys/sysinfo.h. * sysdeps/unix/sysv/linux/gethostid.c: Prevent warning. * sysdeps/unix/sysv/linux/i386/Makefile [$(subdir) == misc] (sysdep_routines): Add ioperm, iopl, and vm86. (headers): Add sys/perm.h and sys/vm86.h. * sysdeps/unix/sysv/linux/i386/sys/perm.h: New file. Contains prototypes for iopl and ioperm. * sysdeps/unix/sysv/linux/i386/sys/vm86.h: New file. Contains prototype for vm86. * sysdeps/unix/sysv/linux/i386/syscalls.list: New file. Add vm86 system call. * sysdeps/unix/sysv/linux/sys/acct.h: New file. Contains prototypes for acct function. * sysdeps/unix/sysv/linux/sys/socket.h: Provide real header file with prototypes. * sysdeps/unix/sysv/linux/sys/sysinfo.h: New file.

Now exported. * stdio/linewrap.c (struct data): Type deleted (moved to linewrap.h). (wrap_stream, unwrap_stream, lwclose, lwfileno, lwoutput, line_wrap_stream, line_unwrap_stream): Use struct line_wrap_data instead of struct data. (lwoutput, line_wrap_stream, line_unwrap_stream): Rename various occurences of `wrap' and `wrapmargin' to `wmargin'. (line_wrapped, line_wrap_lmargin, line_wrap_set_lmargin, line_wrap_rmargin, line_wrap_set_rmargin, line_wrap_wmargin, line_wrap_set_wmargin, line_wrap_point): New functions. * stdio/linewrap.h: New file. * stdio/Makefile (headers): Add linewrap.h.
