Hi all, I tried to compile an example provided with the Boost date time library but kept getting the following error message: "/pssource/current/thirdparty/boost/boost_1_29_0/boost/type_traits/is_void.hpp", line 23: Warning: Too few arguments in macro BOOST_PP_CHECK_2. "/pssource/current/thirdparty/boost/boost_1_29_0/boost/type_traits/is_void.hpp", line 23: Error: BOOST_PP_LIST_FOR_EACH_I_M is not defined. "/pssource/current/thirdparty/boost/boost_1_29_0/boost/type_traits/is_void.hpp", line 23: Error: Use ";" to terminate declarations.

Thanks in advance.
