It is in the mc test case that I posted previously.

You also need to change the PCH support in msvc.jam to:

generators.register [ new pch-generator msvc.compile.pch : H : OBJ PCH : 
<toolset>msvc ] ;
generators.register [ new pch-generator msvc.compile.pch : HPP : OBJ PCH 
: <toolset>msvc ] ;

to allow for stdafx.h or pch.hpp to be used as pre-compiled headers.

NOTE: The line endings in pch.jam appear to be messed up :(.
