Thanks. I think your patch is probably the correct one then. Please can
you submit with a proper changelog.

I wonder if we should be arranging to pass the full set of configure
optons we received down to the subconfigure. That's how projects which
have subtree configures do things (including our own toplevel, tools,
docs, stubdom configure). My concern would be that this is a 3rd party
configure so the scenario is slightly different. TBH I'm no autoconf
expert so I don't know...

Ian.
