Unfortunately, while there is some sentiment for this view, it's not
guaranteed by the Standard (unless the relevant text has changed since
the October draft), so it should not be relied on.  There are two
possible interpretations of the actual wording, neither of which is
internally contradictory:  either #pragma is allowed to change the
rules, or it isn't.  Opinions vary on which interpretation is preferable,
but the Standard doesn't say.
