Hi all,
I'm getting a build error when trying to compile the version of GCJ
merged with Classpath 0.98:

Is there an issue with gcj and the use of covariant return types from 1.5?
The methods in question are StringBuffer.append(char),
StringBuffer.append(CharSequence,int,int) and
StringBuffer.append(CharSequence). All return a StirngBuffer and
override methods with the same signature but a return type of
AbstractStringBuffer in AbstractStringBuffer.
Cheers,
