[Boost-users] [regex] How to pass BOOST_REGEX_RECURSIVE to bjam build process (win32)

Hi, we used to compile boost regex in boost version 1.36 with the following command: bjam.exe -sHAVE_ICU=1 -sICU_PATH=../../../../icu -sBOOST_REGEX_RECURSIVE toolset=msvc-7.1 threading=multi python-debugging=on link=shared variant=debug --without-mpi libs\regex\build When switching to boost 1.38, we realized that BOOST_REGEX_RECURSIVE is not passed/picked up anymore when using the same command (apart compiler version to compile (verified with some added pragma messages): How should this be configured nowadays? Or did it never work that way but the default behaviour changed? Maybe the user-config.jam file should be used, but I didn't find an example of how to do this. Thanks a lot, Chris
