Isn't this a duplicate of #6646?

[abrarov@…]

This cosmetic issue may be considered as an update for #6646.

[Peter Dimov]

The _Interlocked warnings should be fixed by [85994].

[Peter Dimov]

(In [85995]) Remove #pragma intrinsic( _mm_pause ); not needed, not supported on Intel. Refs #6646, #7318.

[Peter Dimov]

(In [86416]) Merged revision(s) 85994 from trunk: Add BOOST_USE_INTRIN_H support; remove #pragma intrinsic, not needed and not supported on Intel. Refs #6646. Refs #7318. Refs #9174.

[Peter Dimov]

(In [86417]) Merged revision(s) 85995 from trunk: Remove #pragma intrinsic( _mm_pause ); not needed, not supported on Intel. Closes #6646, #7318.
