        (stmp-stdio64,stdio64.texi): New targets to optionally add in
        stdio64 info to info files.
        * libc/Makefile.in: Regenerated.
        * libc/configure: Ditto.
        * libc/configure.in: Add configuration variables that are set
        when stdio64 is selected as subdir in configure.host.
        * libc/libc.texinfo: Add optional menu item for Stdio64, based
        on whether STDIO64 flag is set or not.
        * libc/sys.tex: Add optional stdio64 syscalls based on whether
        STDIO64 flag is set or not.
        * libc/include/reent.h[__LARGE64_FILES]: Add new stdio64
        _r sycall routines.
        * libc/include/stdio.h[__LARGE64_FILES]: Add new stdio64 prototypes.
        (FILE): Typedef'd to __FILE instead of struct __sFILE directly.
        (__SL64): New file flag indicating file is opened via fopen64.
        * libc/include/sys/_types.h(_off64_t): Added.
        * libc/include/sys/config.h: For x86-linux, define __LARGE64_FILES.
        * libc/include/sys/reent.h(struct __sFILE64): New file structure
        for 64-bit offset large file support.
        (__FILE): New intermediate type either set to struct __sFILE64 or
        struct __sFILE, depending on whether __LARGE64_FILES is set or not.
        * libc/reent/Makefile.am[HAVE_STDIO64_DIR]: Add new files.
        * libc/reent/Makefile.in: Regenerated.

+FUNCTION
+<<fsetpos64>>---restore position of a large stream or file
+
+INDEX
+	fsetpos64
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int fsetpos64(FILE *<[fp]>, const _fpos64_t *<[pos]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int fsetpos64(<[fp]>, <[pos]>)
+	FILE *<[fp]>;
+	_fpos64_t *<[pos]>;
+
+DESCRIPTION
+Objects of type <<FILE>> can have a ``position'' that records how much
+of the file your program has already read.  Many of the <<stdio>> functions
+depend on this position, and many change it as a side effect.
+
+You can use <<fsetpos64>> to return the large file identified by <[fp]> to a 
+previous position <<*<[pos]>>> (after first recording it with <<fgetpos64>>).
+
+See <<fseeko64>> for a similar facility.
+
+RETURNS
+<<fgetpos64>> returns <<0>> when successful.  If <<fgetpos64>> fails, the
+result is <<1>>.  The reason for failure is indicated in <<errno>>:
+either <<ESPIPE>> (the stream identified by <[fp]> doesn't support
+64-bit repositioning) or <<EINVAL>> (invalid file position).
+
+PORTABILITY
+<<fsetpos64>> is a glibc extension.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek64>>, <<read>>, <<sbrk>>, <<write>>.
