        * configure.host(stdio64_dir): New setting that is used to
        enable building of new stdio64 directory.
        * libc/Makefile.am[HAVE_STDIO64_DIR]: Add support for
        large files.
        (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.

+INDEX
+	_lseek64_r
+
+ANSI_SYNOPSIS
+	#include <reent.h>
+	off64_t _lseek64_r(struct _reent *<[ptr]>,
+		           int <[fd]>, off64_t <[pos]>, int <[whence]>);

+	struct _reent *<[ptr]>;
+	int <[fd]>;
+	off64_t <[pos]>;
+	int <[whence]>;
+
+DESCRIPTION
+	This is a reentrant version of <<lseek64>>.  It
+	takes a pointer to the global data block, which holds
+	<<errno>>.  This function only exists on a system
+        with large file support.
