Thanks!

Oh... you've found a bug!

First, the explanation. The msvc.link generator, which creates EXE, tries to 
create RSP file from all sources. The generator for RSP, defined at the end 
of builtin.jam, accepts all types of libraries. As the result, searched lib 
is considered consumed and added to RSP.

The workaround I have now is to put the following at the end of builtin.jam:

register-linker builtin.response-file : OBJ SEARCHED_LIB STATIC_LIB 
IMPORT_LIB : RSP : <link>shared ;
register-linker builtin.response-file : OBJ : RSP : <link>static ;

Instead of generator declaration that is currently there. Maybe, you can try 
with this change? The modified file is at

http://zigzag.cs.msu.su:7813/working_copy/v2/tools/builtin.jam

It works ok for your test case.

P.S. In fact, I start to think that RSP generator is too fancy and should be 
removed. But that's not for M9 ;-)
