In common English usage, "many" means "a large number."
But in Computer Science, "many" often means "more than one."
i.e. relational databases support either "1:1" or "1:many" relationships.

In the context you describe, the word "many" often means "zero or
more". Therefore, given your definition of "many", there are "many"
people who think that your claim is ludicrous, given the context in
which the word was used in the original post.
Of course, your claim is made as a cheap attempt to take pot-shots at
me (I believe the commonly used term is "Trolling"). Since the censors
(so-called "moderators") of this newsgroup have, on many=B9 occasions,
allowed individuals - including yourself - to do so, yet rejected my
reasoned responses to those pot-shots I have to assume that you will
not see this post.

Footnotes:=20
=B9 Here, many is used in it's common English usage of "a large number".

You say "many compilers" miss these optimisations, yet you cite only 2
examples (Borland, g++). I submit that "two" is not "many".
Since you claim g++ does not perform these optimisations, perhaps you
should volunteer your services to the g++ team, to help improve their
optimizer.
Similarly, since you claim Borland C++ does not perform these
optimizations, perhaps you should volunteer to offer your services to
Borland to help improve their optimizer.

If a copyright notice is more restrictive than the copyright law, it is
the latter that rules what is legal.

Perhaps comp.compilers would be appropriate.

4. The copyright laws in your jurisdiction may differ from those in
the poster's jurisdiction, or in the jurisdiction of any follow-up
poster and therefore some (or all) of your points may not apply.
