[Maypole] -e argument OK isn't numeric in eq (==)

I think it was imported OK :) because Peter didn't say there was a 
warning when it was used earlier on line 76.

There don't seem to be too many places between there and line 98 where 
things could go awry unless there's been some adventurous overloading. 
My money would have to be on something in custom authentication code.

Put us out of our misery, Peter! Where was the problem?

Cheers, Dave
