tests: Conditional compilation of tests (including boost-based unit tests)
To compile tests, code needs to be configured with --with-tests option,
otherwise all tests are disabled.
Tests that are based on Boost's unit test framework are enabled only if
the framework is detected during the configure time.

+# SYNOPSIS
+#
+# AX_BOOST_ASIO
+#
+# DESCRIPTION
+#
+# Test for Asio library from the Boost C++ libraries. The macro requires a
+# preceding call to AX_BOOST_BASE. Further documentation is available at
+# <http://randspringer.de/boost/index.html>.
+#
+# This macro calls:
+#
+# AC_SUBST(BOOST_ASIO_LIB)
+#
+# And sets:
+#
+# HAVE_BOOST_ASIO
