 #
 # SYNOPSIS
 #
 #   AX_BOOST_BASE([MINIMUM-VERSION])
 #
 # DESCRIPTION
 #
 #   Test for the Boost C++ libraries of a particular version (or newer)
 #
 #   If no path to the installed boost library is given the macro
 #   searchs under /usr, /usr/local, /opt and /opt/local and evaluates
 #   the $BOOST_ROOT environment variable. Further documentation is
 #   available at <http://randspringer.de/boost/index.html>.
 #
 #   This macro calls:
 #
 #     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
 #
 #   And sets:
 #
 #     HAVE_BOOST
