Any comments on this bit of Mike's patch...

+int
+darwin_dbx_register_number(n)
+{
+#if 1
+  /* Without -O3, eh-alloc-1.c -m32 fails.  */
+  /* Works! */
+  if (write_symbols == DWARF2_DEBUG && !dwarf2out_do_frame())
+    return svr4_dbx_register_map[n];
+#else
+  /* Works! */
+  if (!(write_symbols == DWARF2_DEBUG
+    || write_symbols == NO_DEBUG))
+    return svr4_dbx_register_map[n];
+#endif
+  return dbx_register_map[n];
+}
