I'll take care of the problem in the 405gp version of these functions, but there
are also 403 specific versions of the functions.  I've seen various people on this
mailing list posting about 4xx processors (other than 405), but I haven't figured
out if there is anyone who is at the center of 401 and/or 403 development and
haven't found the info in the various FAQs yet.  Is there any such person?
