That's not only a proper use of __*, but the recommended one.

My argument is that the entire Standard must be conformed to, whether or
not an application happens to actually use #pragma, thus #pragma cannot
change the semantics that rest of the Standard specifies.

However, opinion on this does not appear to be unanimous even among
X3J11 members.  This is another area where a formal interpretation
ruling would be nice.
