Perhaps we should move this class of warning from -Wall to -Wextra?
(I'd prefer that over introducing yet another option -Wstandard.)
That would be my preferred solution -- by far. But, my understanding
is that that would provoke a riot so I am willing to compromise by introducing
a new warning switch (even if I dislike that thought.)
Hopefully, it is it is going to be the default, most people would not have
to learn yet another GCC switch.
I would not like to see -Wall lose warnings that it has now, and I think
others would find that a problme. -Wextra may be too much for that same
group of people.
We have certainly found it useful to have three general categories of
warnings in GNAT
a) the warnings that are on by default
b) the warnings that are turned on by -gnatWa (similar to -Wall)
c) all warnings (tunred on by -gnatw.e)
