thread-safe increment and decrement

I have written a set of smart pointer classes that improve on the ones
provided by boost:

Now I would like to make these classes portable across environments. To do
that I need a semi-portable way to increment and decrement reference counts
in a thread-safe manner.

Under Windows I use InterlockedIncrement and InterlockedDecrement. But I see
that boost uses simple ++ and -- even under Windows. Is that thread-safe
with the supported Windows compilers?
