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_at_kipple:~/tmp$ g++-4.2 test.cpp -I ~/boost/archive/boost_1_48_0
-Wconversion
daniel_at_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
