Yes.  However, full autoconfiguration is only invoked from the
Boost.Python Jamfile (libs/python/build/Jamfile.v2).  If BGL's Jamfile
doesn't do something to ensure that Boost.Python's Jamfile is loaded
before it looks for Python being configured, or duplicate the few
lines of autoconfig logic in Boost.Python's jamfile (I can't find the
Jamfile.v2 that builds the BGL python bindings, so I can't verify),
autoconfiguration won't kick in.

It's very standard if your main disk is D:.  That's where the Python
installer puts it.

Primarily, it looks in the windows registry for information about
where Python was installed.

You need a space before the semicolon.

That should be unnecessary.
