[Boost-build] Override expected output files of lib target

Hello,

i have attached a test project for the build problem if the dll exports 
no functions in the case of a windows message dll.
In this case the microsoft linker generates no lib file, but boost build 
searches for it and so repeatedly builds the dll.
In the zip file you find three log files.
first_build.log: shows the output for the first b2 invocation.
builddir_first_build.log: shows the content of the build directory and 
it misses the lib file.
builddir_first_build.log: there is the line "made+	missing	 
<pbin\msvc-10.0\debug>my_message_dll.lib"

I there a way to override the targets boost build expects to be generated?

Thanks in advance

Regards,

bernhard
