Would it be better to keep each change localized? at first I didn't
really care for this approach that was taken in patch 1, but compared
to copy-pasting multiple lines of code, it might be simpler to deal
with fine-grained modifications, like this:

                         if (Rflag && (Lflag || Hflag))
+                               #ifdef __rtems__
+                               (void)
+                               #endif
                                 (void) stat(*argv, &tmp_stat);
