Does anybody remember - what was the compiler version again and what

Guenter reported that "The problem is seen with gcc 11.3.0, but not with gcc
12.2.0 nor with gcc 10.3.0."

Thanks.

I added a GCC11_NO_ARRAY_BOUNDS symbol to match the existing
GCC12_NO_ARRAY_BOUNDS one, and to half-way document this thing.

I obviously don't see this warning myself, so my commit is "blind",
but looks completely obvious.

Famous last words.


Tested working.
