~/% clang --version
clang version 3.4 (trunk)
Target: amd64-portbld-freebsd9.1
Thread model: posix

~/% uname -a 
FreeBSD ninga.iciti.internal 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec  4 09:23:10 UTC 2012     root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

>Description:
fscd.c:977:13: error: variable 'sendstr' is used uninitialized whenever 'if' condition is false
      [-Werror,-Wsometimes-uninitialized]
        } else if (strcmp(arglst[0], "status") == 0) {
                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
fscd.c:984:16: note: uninitialized use occurs here
        send(sock_fd, sendstr, strlen(sendstr), 0);
                      ^~~~~~~
fscd.c:977:9: note: remove the 'if' if its condition is always true
        } else if (strcmp(arglst[0], "status") == 0) {
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
fscd.c:934:15: note: initialize the variable 'sendstr' to silence this warning
        char *sendstr;
                     ^

>How-To-Repeat:
Try to build fsc with recent clang (clang-devel-3.4.r181598_3)
>Fix:
clang recommends initializing the variable 'sendstr'.  I have not tried this.
