According to K&R2 (p229):

"comments are replaced by a single space."

So it is part of ANSI, not just the usual implementation.  Compilers that
do generate "number" are not ANSI-conformant.

The subject line for this thread is misleading, by the way.  "Nested
comments" are something different than what you're talking about.
"Comments embedded in identifiers" would be a better terminology.

pfalstad@phoenix.princeton.edu   The Germans are disputing it! Hegel is
arguing that the reality is merely an a priori adjunct of non-absolutistic
ethics; Kant, by the categorical imperative, is holding it ontologically
exists only in the imagination; and Marx is claiming it was off sides.
