--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note for long long, you can use -Wno-long-long which is documented here: https://gcc.gnu.org/onlinedocs/gcc-12.2.0/gcc/Warning-Options.html#index-Wlong-long Been around since 3.1: https://gcc.gnu.org/onlinedocs/gcc-3.1.1/gcc/Warning-Options.html#Warning%20Options -Wlong-long Warn if long long type is used. This is default. To inhibit the warning messages, use -Wno-long-long. Flags -Wlong-long and -Wno-long-long are taken into account only when -pedantic flag is used.
