Damn, sorry.  I should be able to get Chris Clark (the author) to relicence
this -- I'm sure his intention was not to be incompatible with the GPL.

In the meantime, I think that we're OK, because Xenstored is licenced under
the LGPL, not the GPL, and that's the only thing that uses hashtable.c at the
moment.

Not that I'm aware of.
