Exactly!

The longer we continue to work on egcs-1.0.x the longer it will be
before we can deal with egcs-1.1.

Quite a bit of my time to work on egcs is already spent on egcs-1.0.x,
and as a result work on the mainline has slowed.  We need to wrap up
egcs-1.0.x then focus 100% of our effort on egcs-1.1.
