There is a fix for this in root/boost/python/detail/config.hpp:

// Work around the broken library implementation/strict ansi checking 
on some
// EDG-based compilers (e.g. alpha), which incorrectly warn that the 
result of
// offsetof() is not an integer constant expression.
# if defined(__DECCXX_VER) && __DECCXX_VER <= 60290024
#  define BOOST_OFFSETOF(s_name, s_member) \
        ((size_t)__INTADDR__(&(((s_name *)0)->s_member)))
# else
#  define BOOST_OFFSETOF(s_name, s_member) \
        offsetof(s_name, s_member)
# endif

Wouldn't it make sense to move this to the top-level config.hpp
(Jens?)?
