I get errors when trying to compile RELENG_9 with clang. Is clag suppose
to work when it comes to compiling the OS or am I missing something:
clang -O2 -pipe -DUSE_GZIP=1
-I/usr/src/usr.sbin/sysinstall/../../gnu/lib/libodialog -I. -std=gnu99
-fstack-protector -Wsystem-headers -Werror -Wall -Wno-format-y2k
