[Syron]

http://commits.kde.org/kdevelop/f812a2c7bf10ea3fdd3628b94cd689576ea21c4b

This does not compile:
kdevgit/kdevelop/languages/cpp/cppduchain/declarationbuilder.cpp: In 
member function ‘virtual void 
DeclarationBuilder::visitDeclarator(DeclaratorAST*)’:
kdevgit/kdevelop/languages/cpp/cppduchain/declarationbuilder.cpp:370:13: 
error: ‘class KDevelop::Declaration’ has no member named 
‘setExplicitlyDeleted’

Furthermore, I cannot find declarations for "{set|is}ExplicitlyDeleted" 
anywhere.
