Ah, I see. A few animals running with -Wextra. Whereas in v14+ we
have -Wcast-function-type in the actual tree, which affects people's
workflows more directly. Like my regular machine, or CI, when a
couple of the OSes' house compilers eventually reach clang 16.
I gess we have to decide if it's a matter for the tree, or for the
people who add -Wextra, ie to decide if they want to filter that down
a bit with some -Wno-XXX. Adder already has some of those:
'CFLAGS' => '-O1 -ggdb -g3
-fno-omit-frame-pointer -Wall -Wextra -Wno-unused-parameter
-Wno-sign-compare -Wno-missing-field-initializers -O0',
