I don't think ax_boost_base.m4 is enough to get ENABLE_BOOST -- the prefix ax_
means it's from autoconf-archive.  Of course, somebody might have been lazy
and copied the file from autoconf-archive, then modified it to suit Dune
without renaming it (and the macros therein).  I'd consider that a bug though,
since that wouldn't play nice with a call to ax_boost_base.m4's macros from
somewhere else.

Bye,
Jö.
