Is BOOST_REGEX_RECURSIVE supposed to be a preprocessor macros? Then, this syntax
never worked.

See:

        http://www.boost.org/boost-build2/doc/html/bbv2/advanced/invocation.html

for command line syntax description. If passing this on command line is not
convenient, you can add this define to project requirements, see:

        http://www.boost.org/boost-build2/doc/html/bbv2/advanced/projects.html

Not that user-config.jam is considered a special project, it can define requirements
and all user project inherit these requirements. So,

        project user-config : <define>BOOST_REGEX_RECURSIVE=1 ;

in user-config.jam will work. I do not know if such a board action is appropriate for
you.
