So I am thinking of killing two

1. Test for -fanalyzer, -Wall, -Wextra.

flags that we want anyway.
3. Test for flags automatically enabled by -fanalyzer, -Wall, -Wextra that are

I did that in Gnulib by installing the attached patch. This could greatly
increase compile times due to the -fanalyzer option, so let's keep an eye out
for that.
s/could/does/.
compile time has gone from seconds to minutes for coreutils at least.
I'd be inclined to not enable -fanalyzer by default.
At least not until it matures more.
-fanalyzer didn't find any actual issues in coreutils,
and currently bails on most files (after taking lots of time about it),
as indicated with the -Wanalyzer-too-complex option.
