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 [1] 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" [4]. On looking there just now I find that it says to use bjam, but then goes on to link to the "Getting started guide" [2]. Hence still no mention of "--with-", or even b2.
