Hmm, I don't recall any agreement or conclusions being reached.
I guess I missed that!

(see previous email for compiler versions).

I suppose it depends on what you consider antique. [I recently
downloaded the "first C compiler" from github. Yes, that is an
antique compiler! ;-)] I would call some of the compilers I use
"a bit mature." :-P

Hmm, so are you saying that this patch is not acceptable because
I used a compiler that is no longer supported?
