Broken support for older g++ version

[ulu]

Latest version of asio depends on C++11 feature std::addressof or forces developers to use Boost. C++11 is not supported in older compilers (like g++ 3.2.2). With this dependency I am unable to use asio on mature projects.

I did not found any remark to this dependency or drop of compiler support. Is there an older version which provides support for C++98 and C++03 only compilers?

Asio has always required Boost when targeting C++98 and C++03, and I have no plan to remove this requirement. Not needing Boost when using C++11 is a relatively new feature, and only works because the C++11 standard provides features that were previously only available in Boost, like addressof.
