I see.

But what is your intent?
Are you trying to come up with a single mutex, that is both
statically (lazy) intializeable (i.e. of type POD) _and_ at the same
time default constructible?

This simply is not feasible.

If your intent is to work around the pthread_once this is as
I see it, much easier. Just use a static mutex and condition
to emulate call_once.

Aren't the ability to statically initialize a mutex, and availability of 
call_once just two sides of the same medal?
