Curious about pin declare...

...by asking a simple question...

Why waste the storage space?

A question that implies the GCC compiler does not optimize const declarations. That is not a "simple question".

...I tried to answer your questions...

Your responses are based on a hypothetical compiler. Perfect answers on a C++ standards forum. Or, in a response to a question about portability. The compiler in question is not hypothetical, this is not a standards forum, and the question was not about portability.

I haven't done anything with any intention of insulting you.

I do not feel insulted. Thank you for your concern.

No need to be insulting.

Even though I fail to understand why you feel insulted it makes no difference. I apologize for insulting you.

If you have a technical argument...

I have already stated my position. I will not engage in any argument about a hypothetical compiler. You are free to do as you please.

...bring it on I'm all in for it

"Bring it on"? No thanks.
