You should have seen a warning about ignored target, right?

I think so. It was reported already but I was reluctant to make the change,
because "what happens if you link statically?" concern. Seems like users
need link static libs into shared ones, so it's better to fix gcc.jam. The cvs 
versionIt now reads:

generators.register-linker gcc.link-dll : LIB OBJ : SHARED_LIB : <toolset>gcc 
;

(Because on gcc, you can link shared lib into shared lib as well).

Let me know if this works for you.
