To begin with, I don't see 

#include <boost/type_traits/is_class.hpp>

anywhere in is_class_test.cpp. The "TYPE_TRAITS" macro has no effect on bjam.
The other two boost files included there also have no refence to is_class.hpp, 
AFAIKT.

When I add 'is_class.hpp' as explicit include, I have a different problem. 
When I touch is_class.hpp, and rebuild the test, the is_class_test.cpp file 
is recompiled. However, libtype_traits_init.a is recreated as well. It's 
recreated on all other invocations. Seems like some bad interaction between 
library scanning (-sNOARSCAN=1 fixes that), and TEMPORARY handling (possibly 
some changes I've merged from Perforce). 

I might look into this later, but anyway this is not related to your original 
question.
