Summary: readdir_r() is different on IRIX 5.3

Initial Comment:
When compiling tcl 8.4.7 on IRIX 5.3 with --enable-threads one ends up with
cfe: Error: ./../unix/tclUnixThrd.c, line 837: The number of arguments doesn't agree with the number in the declaration.
     if (readdir_r (dir, ent, &ent) != 0) {
 ------------------^
*** Error code 1 (bu21)

This is because on IRIX 5.3 readdir_r() is

 struct dirent *readdir_r (DIR *dirp, struct dirent *res);

unix/tclUnixThrd.c thushas to be changed on IRIX 5.3 into

#ifdef HAVE_READDIR_R
    ent = &tsdPtr->rdbuf.ent;
/*    if (TclOSreaddir_r(dir, ent, &ent) != 0) {
        ent = NULL;
    }
*/
        ent=TclOSreaddir_r(dir, ent);

#else /* !HAVE_READDIR_R */

ideally the configure tools should detect which version of readdir_r is being used on a given platform.
