They have high false positive rates with few benefits. We regularly keep -Wreturn-type working despite this (see all of the llvm_unreachable after switch statements), but the fix to silence GCC's -Wuninitialized false positives active...

Hi all! Yesterday I upgraded to FreeBSD 10.0-RC1 through freebsd-update. Everything seemed fine until I decided to upgrade my ports today. There was a new version of pkg which built fine up until the linking: ===> Building for pkg-1.2.3 --- all --- ===> libpkg (all) --- objwarn --- --- libpkg.so.1 --- --- objwarn --- Warning: Object directory not changed from original
