I confirmed that including <boost/mpl/print.hpp> on Clang in C++03 mode
**always** produces a warning (i.e. even without using `boost::mpl::print<T>`).
IMHO this issue should be fixed, so I made a PR

I'm not sure this is worth fixing, but we can remove the warning by

#ifdef __has_warning
#if __has_warning("-Wkeyword-macro")

#pragma ...
