In common.h, define func_lib for function objects. In configure.ac, define HAVE_STD_FUNCTION and HAVE_BOOST_FUNCTION. Include function headers in ndnboost.

+<title>Introduction</title>
+<para>The Boost.Function library contains a family of class templates
+that are function object wrappers. The notion is similar to a
+generalized callback. It shares features with function pointers in
+that both define a call interface (e.g., a function taking two integer
+arguments and returning a floating-point value) through which some
+implementation can be called, and the implementation that is invoked
+may change throughout the course of the program.</para>
+
+<para> Generally, any place in which a function pointer would be used
+to defer a call or make a callback, Boost.Function can be used instead
+to allow the user greater flexibility in the implementation of the
+target. Targets can be any 'compatible' function object (or function
+pointer), meaning that the arguments to the interface designated by
+Boost.Function can be converted to the arguments of the target
+function object.</para>
