I'm not sure that ever worked, but in any case:

bjam.exe -sICU_PATH=../../../../icu  define=BOOST_REGEX_RECURSIVE=1 
toolset=msvc-7.1  threading=multi  python-debugging=on  link=shared 
variant=debug  --without-mpi  libs\regex\build

Will do what you want (mixing HAVE_ICU with ICU_PATH isn't such a good idea 
either BTW).

Also BOOST_REGEX_RECURSIVE is the default mode for Boost.Regex under vc-7.1 
anyway, although that changes for more recent VC++ versions.

HTH, John.
