Here is the third (and last) part of the patch. Actually ... this is a 
different patch wet the one proposed before.

In UnresolvedUsingTypenameDecl nodes, the UsingLocation field is not 
initialized in the constructor, nor it is ever accessed, e.g., when 
(de-)serializing the node. The start location for the source range is 
obtained by querying the TypeDecl base class. Hence, the patch simply 
removes this apparently useless source location field.

OK to commit?

Enea.
