There's some expressed interest in having the compiler flag -Wconversion detect at build time certain kinds of potential problems: https://lore.kernel.org/lkml/20250103182532.GB781381@e132581.arm.com/ As feature detection passes -Wconversion from CFLAGS when set, the feature detection compile tests need to not fail because of -Wconversion as the failure will be interpretted as a missing feature. Switch various types to avoid the -Wconversion issue, the exact meaning of the code is unimportant as it is typically looking for header file definitions.
