If it was a working group document, then it was't an ANSI standard
either, and it wasn't actually "dropped". And, as i said, it was
available; since it's non-normative, it doesn't matter much whether
it's published by ISO or not.

If by "not balancing all the tags" you mean omitting some start and
end tags, that may be perfectly valid. Unlike XML, SGML (of which
HTML is supposed to be an example) allows many shortcuts in that
respect for the benefit of human authors.

On the other hand, if you mean things like badly-nested elements such as

<x>some<y>rando m</x>stuff</y>

then it's not valid.

Please pay attention; you even quoted the question that I answered.

The *original poster* asked "How many levels of pointers can you
have?". (I didn't attempt to answer that question.)

Later in the thread, Joachim Schmitz (who is not the OP) asked:

So what does C89 require as the minmum?

That's the question I answered. The answer is 12.

Why bother? Almost nobody uses it. Why reference an almost unused
standard? I can see why you might want to refer to C99 in, say, a
tutorial - just to make people aware that it exists and broadly what
its features are - but otherwise it seems pretty pointless.

<snip>

I my opinion it depends on how much clout the MISRA group has. If they
can effectively force the compiler writers for the chips used in their
domain to conform to C99 then them doing so would be a good thing in my
opinion. However, if the compiler vendors will just ignore it then MISRA
should stick to C95. After all, I don't want my car failing because the
code used a C99 feature that was not properly implemented by the compiler!

The problem is pragmatically speaking the Gcc dialect is very
widely spread. It is far more common than C99. Also there is a
lot of freely available source that uses the gcc dialect.

But you are not stuck with it. "-W -Wall -ansi -pedantic" converts
gcc into a standard C compiler. As I suspect you know.

Many commercial compilers use C99 complaint front ends. It is

I believe the major problem is updating all those libraries.

There are so many people inflating their resumes that the resume of
someone who has not done the same will look anemic by comparison.

On the other hand, my resume is entirely truthful and includes
information on where I'm willing to work, and I can count on one or
two emails a week from recruiters who want me to work jobs I'm not
qualified for in geographically infeasible areas. I suspect the
resume-padding has gotten to such a point that nobody is reading them
at all any longer, and it has become some sort of ritual signalling

I have a significantly higher ratio of job offers to job interviews than
most people I know.
This is mostly because I have trouble getting interviews when looking for
a job; most places where I've been interviewed have seemed to be impressed
with me. I have, on more than one occasion, been discussing this and
said something like "Maybe I need to lie more on my resume", and I've
found it disturbing how many people treat that as a serious suggestion.
(For the curious, a lightly edited version of the resume that got
me my current job is at <http://www.eskimo.com/~dj3vande/resume/>.
Compare with <http://www.seebs.net/res-p.html>.)

Why should I? Most of the previous posters in that thread didn't (if I got

Instead you swear at me, great :-(

Because it's the right thing to do.

What has that to do with it? People will consider you responsible for
*your* posting behaviour, not theirs.

(if I

See above, where he says "you two", so he's not just picking on you.

He shouldn't have done that. But that's his problem, not yours. Learning
how to snip properly is your problem, not his.

Actually the compiler writers do seem to take note of MISRA-C. Many
include MISRA checkers of MISRA- compliant code. However.... MISRA-C is
a coding standard to use with tools that are in use now. That is why
it is based on C90+

Not at all. There are several C99 libraries out there. It is just that
there is no demand for C99 in the real world.

Try to learn to read. I left two attributions, you and Chris Hills, who
are responsible for the back and forth non-trimmed posting. I
specifically said "you two".

Besides, regardless of whether anybody else did or did not trim quotes,
you didn't.
