 using spinlocks requires linking with boost.atomic. whenever linking is
 required, if the target platform does not support a specific atomic<> type
 natively.

 every user of boost.atomic should link with the library, no matter if
 cross-compiling or not.

 I believed that Boost.Atomic was header-only on most of the platforms. I
 don't want to force the user to link with boost_atomic when there is no
 need. Is there a macro that can be tested to know if Boost.Atomic is not
 header only?
