I foudn that the following lines int he following files generates a huge amount of spurious warning in gcc 4.3 with -Wall : /boost/math/special_functions/gamma.hpp line 1264: tgamma1pm1(T z, const Policy& /* pol */) /boost/function_types/detail/pp_retag_default_cc/preprocessed.hpp line 18 BOOST_STATIC_CONSTANT(bits_t, value = ( (::boost::function_types::detail::bits<Tag> ::value & 0x00008000 ) |( ::boost::function_types::detail::bits<RefTag> ::value & 802) )); /boost/function_types/detail/pp_tags/preprocessed.hpp line 56 BOOST_STATIC_CONSTANT(bits_t, combined_bits = (LHS_bits & ~RHS_mask) | RHS_bits ); The later was signaled as a ticket in trac but I wanted to know if it was fixed/merged in the upcoming 1.38. -- ___________________________________________ Joel Falcou - Assistant Professor PARALL Team - LRI - Universite Paris Sud XI Tel : (+33)1 69 15 66 35
