of possible interest to hppa people

I'm not sure of the history of this bug, but it seems not to have
attracted much intersted from porters in the last decade or so

          https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=559639

It may be hopeless, but if someone with a particular interest in hppa
wants to tackle it, please follow up on the bug.  I am nearly certain
that the underlying issue is different now, since racket has changed a
lot in the meantime.
