        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.

        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.

+FUNCTION
+<<tmpfile64>>---create a large temporary file
+
+INDEX
+	tmpfile64
+INDEX
+	_tmpfile64_r
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	FILE *tmpfile64(void);
+
+	FILE *_tmpfile64_r(void *<[reent]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	FILE *tmpfile64();
+
+	FILE *_tmpfile64_r(<[reent]>)
+	char *<[reent]>;
+
+DESCRIPTION
+Create a large temporary file (a file which will be deleted automatically),
+using a name generated by <<tmpnam>>.  The temporary file is opened with
+the mode <<"wb+">>, permitting you to read and write anywhere in it
+as a binary file (without any data transformations the host system may
+perform for text files).  The file may be larger than 2GB.
+
+The alternate function <<_tmpfile64_r>> is a reentrant version.  The
+argument <[reent]> is a pointer to a reentrancy structure.
+
+Both <<tmpfile64>> and <<_tmpfile64_r>> are only defined if __LARGE64_FILES
+is defined.
+
+RETURNS
+<<tmpfile64>> normally returns a pointer to the temporary file.  If no
+temporary file could be created, the result is NULL, and <<errno>>
+records the reason for failure.
+
+PORTABILITY
+<<tmpfile64>> is a glibc extension.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<getpid>>,
+<<isatty>>, <<lseek64>>, <<open64>>, <<read>>, <<sbrk>>, <<write>>.
+
+<<tmpfile64>> also requires the global pointer <<environ>>.
