Sorry, I misunderstood the question. The difference about the noisiness between CC and HOSTCC is just comes from the amount of source code. Adding -Wshadow to KBUILD_HOSTCFLAGS emits another warning in Kconfig. Of course, it is easy to fix. But, I just started to think this option is a kind of harsh... -- Best Regards Masahiro Yamada
