Yes, I get confused by it too, which is how I noticed this problem.  But 
I'm not sure how to fix this.

I wonder if it's possible to check the set of variables which exist 
after evaluating the cygport file, and warn if there are unexpected ones.

(Any existing uses of temporary variables inside a cygport file would 
have to be unset before it exits to avoid warning about them, but that 
seems a fair price to pay...)
