I see the list “frameworkClasses” is meant to be populated during the make 
process running “nm *.o -Pg” as part of EXTRACT_CLASS_NAMES_COMMAND. Defined in 
target.make, this command is used to look for lines output from nm starting 
with “__objc_class_name”. 

However, when I tried running nm manually on the objects in ProjectCenter.obj, 
grep shows *no* lines containing __objc_class_name.

@David do you have any insight as to why the names of the classes are not be 
appearing?  Should they be appearing?
