Something is fishy, cause I don't see a regression, but rather a minor
improvement.  Admittedly, the spec92 test harness is mysteriously bombing
out on me, but running it by hand I get

So.  Can you run the test again?  Or see what I've done wrong
configuring spec92 in /nfs/happy/smile/rth/spec92/? 

Grr.. didn't have these sorts of problems with spec95...
