Hello,

from looking at [1] i understood that there is no lock-free
implementation of shared_ptrs on solaris.

When snooping around in the source i noticed that there is a
./smart_ptr/detail/atomic_count_solaris.hpp
It is using the solaris specific <atomic.h> to implement an
atomic counter.

frank_at_dexter:~/boost_1_40_0/boost$ find -type f | xargs grep
atomic_count_solaris.hpp
./smart_ptr/detail/atomic_count_solaris.hpp://
boost/detail/atomic_count_solaris.hpp

But apparently it is not in use. I am currently wondering why?

KR,
  Frank
