Hi ,
I don't think difference is due to 1.44 and 1.48 because I get same warnings with both version. It seems to me that you don't get warnings because of older g++ compiler than what we are using. Would you or anyone else on the list happen to have access to newer version of g++ ?
can someone simulate what I am seeing ?
I tried it on OS X with boost 1.48, I got no warning for apple's gcc 4.2, but did a get a warning for macport's gcc 4.4: daniel@kipple:~/tmp$ g++-4.2 test.cpp -I ~/boost/archive/boost_1_48_0 -Wconversion daniel@kipple:~/tmp$ g++-mp-4.4 test.cpp -I ~/boost/archive/boost_1_48_0 -Wconversion [snip trail] test.cpp:9: instantiated from here /Users/daniel/boost/archive/boost_1_48_0/boost/mpl/aux_/integral_wrapper.hpp:73: warning: the result of the conversion is unspecified because '-0x00000000000000001' is outside the range of type 'boost::numeric::int_float_mixture_enum'
