[no%]extdef

[Do not] Search for template definitions in separate source files. 

[no%]geninlinefuncs

[Do not] Generate unreferenced inline member functions for explicitly instantiated class templates. 

[no%]wholeclass

[Do not] Instantiate a whole template class, rather than only those functions that are used. You must reference at least one member of the class; otherwise, the compiler does not instantiate any members for the class.
