suggestion to remove warning of comparison about singned and unsigned

[Philipp Huber <phu@…>]

I haven't got into mpl to actually understand, what the lines are doing I suggest to correct, they actually don't make sense to me. However, they are causing a long template warning in the context of using boost::text_archive about comparing unsigned with signed which causes eclipse to interpret it as an error for unknown reasons.

so I suggest the following patch (the revision numbers are those of my own repository):

Index: boost/mpl/print.hpp =================================================================== --- print.hpp (revision 1772) +++ print.hpp (revision 1773) @@ -57,7 +57,7 @@

# if defined(EDG_VERSION)

aux::dependent_unsigned<T>::value > -1

# else

• sizeof(T) > -1

+ sizeof(T) >= 0

# endif

};

#endif

This warning is intentional. mpl::print is supposed to generate a warning. See http://www.boost.org/doc/libs/1_40_0/libs/serialization/doc/rationale.html#trap. Note that this was downgraded to a warning. For some reason the rationale was removed from the documentation.
