>Description:
i believe the following assignment is unnecessary and can be removed:
/usr/local/bin/clang -fpic -DPIC -O2 -pipe -march=core2 -DSTRIP_FBSDID
-I/usr/git-freebsd-head/lib/libc/include
-I/usr/git-freebsd-head/lib/libc/../../include
-I/usr/git-freebsd-head/lib/libc/amd64 -DNLS -D__DBINTERFACE_PRIVATE

-fstack-protector -Wsystem-headers -Wall -Wno-format-y2k -Wno-uninitialized
-Wno-pointer-sign -c /usr/git-freebsd-head/lib/libc/resolv/res_send.c -o
res_send.So
/usr/git-freebsd-head/lib/libc/resolv/res_send.c:1105:7: warning: explicitly

run buildworld with clang (or clang tot in my case) as compiler.
