First up, note that clang 13 does not produce those "variable foo set but not used" warnings by default. They need to be enabled by -Wunused-but-set-variable or, more typically, as part of -Wall.
Here are the remaining warnings seen in a "make build": bin/ksh required arguments to macros libexec/spamd ifdef'ed out error handling usr.bin/cvs unfinished code usr.sbin/vmd arguments to debugging macros Third-party code: gnu/lib/libcxxabi sbin/unwind/libunbound gnu/usr.bin/clang gnu/usr.bin/binutils gnu/usr.bin/binutils-2.17 gnu/usr.bin/perl -- Christian "naddy" Weisgerber na...@mips.inka.de
