Hello, i tried to use Aspectc++ with boost, and it failed to parse such token as: @#ifdef a simple grep show me several occurrence of this: ultimatetrader% grep -nr '@#if' /usr/include/boost/* /usr/include/boost/type_traits/detail/is_mem_fun_pointer_impl.hpp:788:@#ifndef BOOST_TT_NO_ELLIPSIS_IN_FUNC_TESTING /usr/include/boost/type_traits/detail/is_mem_fun_pointer_impl.hpp:793:@#if !defined(BOOST_TT_NO_CV_FUNC_TEST) /usr/include/boost/type_traits/detail/is_mem_fun_pointer_impl.hpp:803:@#ifndef BOOST_TT_NO_ELLIPSIS_IN_FUNC_TESTING /usr/include/boost/type_traits/detail/is_function_ptr_tester.hpp:580:@#ifndef BOOST_TT_NO_ELLIPSIS_IN_FUNC_TESTING /usr/include/boost/type_traits/detail/is_function_ptr_tester.hpp:584:@#ifdef BOOST_TT_TEST_MS_FUNC_SIGS /usr/include/boost/type_traits/detail/is_function_ptr_helper.hpp:215:@#ifndef BOOST_TT_NO_ELLIPSIS_IN_FUNC_TESTING i don't think the '@#ifdef' is standart c++, is it? how come c++ compilers (at leat g++) don't fail on these tokens? i use libboost-dev 1.32.0+1.33.0-cvs20050727-1ubuntu1, if it helps.... regards, -- Guillaume Desticourt
