Boost is now required (ticket:370). Boost 1.33 is required, which is a pretty arbitrary number. I happen to have 1.33 installed on my machine. If someone can test that it works with an earlier version, I am more than happy to soften this requirement. Currently, there is no linking to Boost. I added a file yat.am that is included in most of our Makefile.am, to avoid parallel modifications.

5	# OBSOLETE MACRO

7	# Use AX_BOOST_BASE in combination with library-specific macros.

9	# SYNOPSIS
10	#
11	# AX_BOOST([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
12	#
13	# DESCRIPTION
14	#
15	# Test for the Boost C++ libraries of a particular version (or newer)
16	#
17	# If no path to the installed boost library is given the macro searchs
18	# under /usr, /usr/local, and /opt, and evaluates the $BOOST_ROOT
19	# environment variable. Further documentation is available at
20	# <http://randspringer.de/boost/index.html>.
21	#
22	# This macro calls:
23	#
24	# AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
25	# AC_SUBST(BOOST_FILESYSTEM_LIB)
26	# AC_SUBST(BOOST_PROGRAM_OPTIONS_LIB)
27	# AC_SUBST(BOOST_THREAD_LIB)
28	# AC_SUBST(BOOST_IOSTREAMS_LIB)
29	# AC_SUBST(BOOST_SERIALIZATION_LIB)
30	# AC_SUBST(BOOST_WSERIALIZATION_LIB)
31	# AC_SUBST(BOOST_SIGNALS_LIB)
32	# AC_SUBST(BOOST_DATE_TIME_LIB)
33	# AC_SUBST(BOOST_REGEX_LIB)
34	# AC_SUBST(BOOST_UNIT_TEST_FRAMEWORK_LIB)
35	#
36	# And sets:
37	#
38	# HAVE_BOOST
39	# HAVE_BOOST_FILESYSTEM
40	# HAVE_BOOST_PROGRAM_OPTIONS
41	# HAVE_BOOST_THREAD
42	# HAVE_BOOST_IOSTREAMS
43	# HAVE_BOOST_SERIALIZATION
44	# HAVE_BOOST_SIGNALS
