[Dune] #if HAVE_BOOST fails in dune-istl

I wanted to state that calling ax_boost_base.m4 might cause the trouble. 
So please check whether you do it. Do only use dune_boost_base.m4 
because only that test sets BOOST_ENABLE.

Have you included BOOST_CPPFLAGS and BOOST_LDFLAGS in your Makefile.am 
for the program?

Bye
Christoph
