The above suggests that the option will be available with gcc 11.3.0.
Information available in public suggests that it will be introduced
with gcc 12.0.
The point here, I think, is to list the minimum gcc version.
It is going to be a long time until gcc 12.0 is the minimum version,
so I think it makes sense to list the minimum version number for
each compiler here.
However, it may make sense to add some reference indicating that
support will indeed be added with gcc 11.3.0, and not only starting
with gcc 12.0 (and maybe wait with applying this patch until it is
actually available in gcc and can be confirmed to work as intended).
