===> libexec/ftpd (all)
clang -O2 -pipe  -DSETPROCTITLE -DLOGIN_CAP -DVIRTUAL_HOSTING 
-I/usr/src/libexec/ftpd -Dmain=ls_main

-Wno-uninitialized -Wno-pointer-sign  -o ftpd ftpd.o ftpcmd.o logwtmp.o 
popen.o ls.o cmp.o print.o util.o -lutil -lcrypt -lopie -lmd -lm -lpam
clang: warning: argument unused during compilation: '-std=gnu99'
