Well, it's simpler than C99 or C11, yes.

Alas, "simplicity" is heterological. It is extraordinarily difficult to 
pin down what we mean by "simplicity". Nevertheless, it is often 
possible to recognise it when we see it. I would regard the fact that 
(say) the plethora of integer types has made C more complicated as 
self-evident, but would you? I don't know.

Yes. C90 is available on pretty much any platform, even those that the 
mainstream has passed by. So those out in the eddies, so to speak, can 
still compile C90 programs, but they may not be able to compile C99 
programs. (I accept that the number of people in this category is almost 
certainly diminishing, but I know that it's more than 0.)

Yes.

I think it's (realistically speaking) almost impossible to write a 
/useful/ strictly conforming program in either dialect. Anyway, I can 
only speak from my own experience but I find it easier both to read C90 
and to write C90 than to read or write C99 programs (if you discount 
those C99 programs that are also C90 programs). That's a general 
observation - to back it up would take more time than I care to invest.

Yes. Let's do some indirection. Let p = &C89. ANSI standardised *p, and 
ISO adopted *p in 1990, and *p became widely portable. If p had 
originally been &C99, then we'd have a widely portable C99 language, and 
my beef with C99 (or at least *that* beef) would be non-existent.

Actually, no. That is the *impression* I get. I don't think the 
impression accurately reflects your intent. Nevertheless, it is the 
impression I get. I therefore have to consciously reject that impression 
when replying to you, knowing that of course you're not trying to offend 
me, but I may not always be successful in doing this.

In elder days, Usenauts would write in an elaborately polite (and 
self-consciously anachronous) style, precisely because they knew this 
problem existed and wished to find a way to sidestep it. I am given to 
understand that it worked quite well. Nevertheless, it appears to have 
fallen by the wayside. That might be a shame.
