The point was that bulk merges (regardless of where they come from) are a
particularly bad way to sync the official GNU sources with some other
source base.  I was just using the merges you did as an example.  The
bulk merges I used to do from the gcc2 sources before gcc2 deveopment
finally died were just as disruptive.
