That's one of the reasons I like C99 and C11, and look forward to
C23. Once implemented, they don't change either.
I agree with all your are arguments on this,

I *don't* think C90 is different. I think C90 is exactly the

I'd like to understand the point you're trying to make.

Being different is a transitive relationship.  C90 is different
"from later C standards".  You say that C90 is "exactly the same"
-- as what?  As itself?

Yes. And nothing else has that quality of being C90.

C99 is also exactly the same as itself.

 I hope that was a typo.  If you really meant that C99 is different from
C99, I suggest that requires a bit more explanation.

Typo, of course. (9 is next to 0.) Alas, my typo-free days are over.

Obviously C90, C99, and C11 are all different from each other.
You seem to be suggesting that C90 is special in some way that C99
and C11 are not.

Yes. Nothing magical, of course. But C90 was there first and is (fairly literally) universal as no other dialect is. It would be a mistake to lose that.

If that's an accurate summary of your opinion,
can you explain it?

Not sure I can be any clearer than I already have been, which seems to have been about as clear as mud. Ah well.

 And if it isn't, just what are we talking about?

Maybe I'm just being grumpy out loud instead of muttering dark imprecations into my coffee mug.
