Looking at Boost.TypeTraits documentation it seems that boost/type_traits/ make_signed.hpp was added in version 1.35.0, but I can't find any reference to that change in the release notes.
Which was the first Boost release that included make_signed?
It was added on the 10th Sept 2007, you should be able to figure out the first release after that. HTH, John.
