The <define> and <include> options are in a response file associated 
with the cpp file. Thus, if you have test.cpp, the response file will be 
in the build directory (e.g. bin/msvc-7.1/release/test.cpp.rsp).

Are you getting any build problems due to _DEBUG not being defined?

NOTE: You shouldn't need to specify _DEBUG as the debug/release settings 
should be taken care of by the variants, e.g.:

    $ bjam debug

Volodya/Rene/Dave: Is there a reason why variant debug doesn't define 
_DEBUG, but variant release defines NDEBUG. VC projects define _DEBUG 
for release builds.
