 Running the accumulators tests with VC9 on warning level 4 produces quite
 a few warnings:

 assignment operator could not be generated:
 {{{

 unreferenced formal parameter:

 }}}

 Unfortunately these are a bit difficult to spot in the logs as they get
 buried under loads of 4512 warnings from fusion, random, and others :(
