This is a heads up for anyone with code (outside of ON and SFW)
that uses pthread_once() with an initialization like this:

pthread_once_t once_control = { PTHREAD_ONCE_INIT };

The extra braces are a recommended workaround for the
problem described in CR:
    6611808 pthread_once() intializer triggers GCC warning

With the push of the fix for 6611808 that I did today, the
workaround is no longer needed, and will cause a build failure
on machines with the fix installed.

The unfortunate code should be reset to the proper:

pthread_once_t once_control = PTHREAD_ONCE_INIT;

This does not affect the ON and SFW consolidations.
There are no instances of this in those consolidations.
