The choice OPTION=atomic enables use of atomics for updates to

The choice OPTION=mutex enables use of a mutex to synchronize updates
to <code class="classname">shared_ptr</code> reference counts.
If the compiler's thread model is "single" then this option has no
effect, as no synchronization is used for the reference counts.
The default is OPTION=auto, which checks for the availability of
compiler built-ins for 2-byte and 4-byte atomic compare-and-swap,
and uses OPTION=atomic if they're available, OPTION=mutex otherwise.
This option can change the library ABI.
If the library is configured to use atomics and user programs are
compiled using a target that doesn't natively support the atomic
operations (e.g. the library is configured for armv7 and then code
is compiled with <code class="option">-march=armv5t</code>) then the program
might rely on support in libgcc to provide the atomics.
