I'm sorry I didn't reply to this at the time, Andrew, but
thanks for the explanation. Also, in reply to my post on 28
May, you suggested that rpcemu-recompiler might not have
been set as an executable; in fact it had been.

Another apology for my lack of a reply. I'm aware that bugs
can't be fixed unless they're reported and I'll certainly
do so if and when I find any. However, I'm hardly a power
user and so might not come across (m)any bugs at all.
