It means you have another variable named 'u' in the same function
declared somewhere before that foreach loop. The theory is that many
times these are bugs, and when they are they can be hard to spot.
I'm not totally enamored with the feature myself, since I don't recall
ever really been bitten by it, but I have happily shadowed variables in
the past when it suited me. Especially little dummy counter/placeholder
variables like your 'c' above.
But anyway, that's what the error means. Just rename 'c' to c2 or cc or d.
