Is there a way to use QUICKFIX 1.14 if I don't have support for C++11?

We are planning to use QUICKFIX 1.14, but most of our stuff is compiled using gcc 4.1 which does not support C++11.

While compiling QUICKFIX 1.14 I realised that it requires C++11 support (it uses std::shared_ptr).

What are my options here?

(Currently I am changing the std::shared_ptr usages to boost::shared_ptr)

Is there any other cleaner solution?
