Comment (by ryandesign):

 It's not that something suddenly broke. It's that something has always
 been wrong in the code, and the compiler was warning about it, and now the
 developers of the compiler consider the problem to be so serious that it
 has been elevated from a warning to an error. I don't, therefore, think
 the best course of action is to downgrade the error back to a warning
 again. Instead, the problem should be fixed properly (by the developers)
 so that the error or warning does not occur.
