Right. The defaults have been changed somewhat.

I knew I didn't want to build everything (I remember from last time that it takes ages, and I don't need anything else) so I followed the link to the Boost.Build Documentation  to find how to specify just regex. As noted above that page doesn't mention "--with-", so the obvious option was just to list "regex", with the result as previously noted.
The --with-xxx option is listed farther down
in the Getting Started Guide.
It isn't listed in the Boost.Build documentation because
it's project specific.
> What I had not done at that time was to look at regex's own page on "Building and Installing the Library" . On looking there just now I find that it says to use bjam, but then goes on to link to the "Getting started guide" . Hence still no mention of "--with-", or even b2.
