I believe they are referring to newer versions of GCC v.2, i.e. versions 
later than 2.95 but earlier than 3, such as 2.96.  These versions were 
not official releases; they were development snapshots of the progress 
towards version 3.  It is understandable, therefore, that they have 
poorer optimization.
