See #410 for a tentative solution that commented out the variable names. Note that the NatSpec documentation for the variables had to be removed, which is not really acceptable.

The proposed solution is to add a no-op mention of the variables. I think simply adding a statement for each variable works: from_; value_; data_;.

I don't get these errors on 0.4.18 after running truffle compile. What is your complication command?

True, this was fixed in #576!
