I'm in the same boat. Maybe it's time for someone to post a summary/update
on the #pragma question.
I have two questions, both of which were probably already addressed.
1. A #pragma causes an implementation to behave in an implementation-defined
manner. Could that include, for example, following unsigned-preserving
promotion rules, or must the behavior still be ANSI?
2. A strictly conforming program shall not produce output dependent on
any implementation-defined behavior. Does it follow that a strictly
conforming program shall not use a #pragma?
