------- Comment #2 from mueller at gcc dot gnu dot org 2008-06-10 22:14 ------- so the code should be changed to
#elif defined(BOOST_PP_ITERATION_DEPTH) && BOOST_PP_ITERATION_DEPTH() == 1 ? it is confusing that #elif behaves more like "#if" and not like "#else\n#if" -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36453
