I became a problem with my (Conal's) suggested patch on a mac. When 
compiled with optimization the code was so blown up that it could no 
longer be linked on a mac. (The problem does not occur if only isEmpty 
is changed as suggested before.)

Unfortunately the example is large and takes ages to be reproduced and 
it took me an age to find that the cause was my change to our version of 
HughesPJ.hs.
