Can you do to cw.jam, and in the last action, "link.dll", 
remove the space character between

   -f

and

  "$(DEF_FILE)"

so that the command line contain

  -f"$(DEF_FILE)"

without any spaces. This will make this part of command line to 
disappear when there's no def file set. Now, the command line is something like:

    ... -f  @"../../../bin.v2/libs/filesystem/build/cw-9.4/debug/libboost_filesystem-cw94-gd-1_34.so.1.34.0.rsp"

so maybe the linker is treating all object files as def files and that leads to the problem?

Thanks,
