[Boost-users] Serialization of optional<std::string>

As part of upgrading a product to a later version of boost the compilation
has tripped up on serialization of a boost::optional<std::string>.

The /optional.hpp/ header now has the comment:

...and this fires for std::string.

What, if any, is the recommended way forward for this?

An example code snippet to illustrate:

Previous version of boost: 1.50; new: 1.6x
Compiling with g++ 4.6.4 (although same problem with 4.8.5): -W -Wall
-std=c++0x...
(The real code is actually using the portable_binary_archive, but let's
avoid muddying the waters at this stage :)
