I have started doing something similar, but I now have a <resource-only> 
feature (see my original post).

It's not the response file logic -- it is the DLL generator:

    generators.register-linker msvc.link.dll
       : OBJ SEARCHED_LIB STATIC_LIB IMPORT_LIB
       : SHARED_LIB IMPORT_LIB
       : <toolset>msvc ;

The issue is that the second IMPORT_LIB (the target) is not being 
generated in this instance. This is related to Alexey Pakhunov's MIDL 
support - i.e. wanting to have optional targets (who's absence doesn't 
cause a rebuild).
