Then I would ask those who hold the first position this:
"Identifiers like _Imaginary_I and _Exit are already covered by the very
first words of clause 7.3.1/1 ("Each header declares or defines all
identifiers listed in its associated subclause"), so why would the
additional text about optionally allowing reserved identifiers be needed?"
As additional evidence for the second stance, I would give this quote
from K&R2 (Appendix B):
<quote>
External identifiers that begin with an underscore are reserved for use
by the library, as are all other identifiers that begin with an
underscore and an upper-case letter or another underscore.
