Here is some ticket that already contains a valid patch and test * mpl::zip doesn't support metafunction use https://svn.boost.org/trac/boost/ticket/1992 * Various unused args warning removal in ASIO : https://svn.boost.org/trac/boost/ticket/1341 * Various gcc warning in numeric https://svn.boost.org/trac/boost/ticket/1338 Other things. I've submitted some MPL::switch_ correction and addition here: https://svn.boost.org/trac/boost/ticket/2249 Now I'm not sure if the fix is what switch was really about after second thoughts. So can soemoen confirm I didn't modified the intended semantic. -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35
