Great, thanks Gavin! (I owe you a beer!)

I re-arranged PrepareStmt as you suggested, as well as
ExecuteStmt, and the conflicts have disappeared. I'm not sure
if the new syntax is ideal, but I'm happy to leave it as it is
until I've got the patch mostly working. I'd welcome any
suggestions for improvements to the syntax that still allow
for sane parsing.

Thanks again,

Neil
