>From gtkrc.c:

  var = g_getenv("GTK_RC_FILES");
  if (var)
    {
      files = g_strsplit (var, G_SEARCHPATH_SEPARATOR_S, 128);
      i=0;
      while (files[i])
	{
	  gtk_rc_add_default_file (files[i]);
	  i++;
	}
      g_strfreev (files);
    }

(SEARCHPATH_SEPARATOR is ':' on unix and ';' on Win32)

I don't really see a point in the command line argument, but if there
is a problem it solves, it could be added.
