We compile as much as possible from source, so we are not affected by 
this change.

I searched for "abstract and does not override abstract method connect" 
and "abstract and does not override abstract method peekData", but got 
no relevant hits.  But this change was made so long ago that search 
engine coverage might be spotty, so the fact that no one reported 
running to the source code incompatibility does not prove that there is 
no code out there that relies on the pre-1.4 binary compatibility 
currently provided.
