It works, thank you.

The autolinking feature still tries to link (lib)boost_bzip2-vc71-mt-1_33.lib,
so in addition to omitting NO_COMPRESSION... I had to define the preprocessor
symbol BOOST_IOSTREAMS_NO_LIB in my project settings and add
boost_iostreams-vc71-mt-1_33.lib manually (this works because both bzip2.cpp and
zlib.cpp are be compiled into (lib)boost_iostreams-vc71-mt-1_33.lib).

I also tried to add -sBZIP2_SOURCE=... and -sZLIB_SOURCE=... to the bjam call
to let bjam create libboost_bzip2 and libboost_zlib. Unfortunately, this does 
not seem to create the dll versions.
