Library is potentially incompatible with Boost 1.8

I am trying to build the library but I get the following compilation errors:

/home/.../shared_memory/src/locked_condition_variable.cpp: In member function 'bool shared_memory::LockedConditionVariable::timed_wait(long int)':
/home/.../shared_memory/src/locked_condition_variable.cpp:64:16: error: 'boost::posix_time' has not been declared

These issues were resolved when I added the #include <boost/date_time/posix_time/posix_time.hpp> header to shared_memory.hpp. There are other compilation issues that are also resolved by adding the appropriate headers.

It has been a while and there is no reply. I tried doing a pull request but I got an unauthorized error. Since there is no support, I will post a diff of my changes in case anyone faces the same issue I did.
