Does anyone regularly build HEAD with clang?

I've noticed that it's been broken for about a week as a result of:

--- /usr/src/lib/libc/../../include/rpc/rpcb_clnt.h.orig	2012-02-12 22:42:29.000000000 -0800
+++ /usr/src/lib/libc/../../include/rpc/rpcb_clnt.h	2012-02-12 22:41:27.000000000 -0800
_at__at_ -66,7 +66,7 _at__at_
 		       const struct netconfig  *, const struct netbuf *);
 extern bool_t rpcb_unset(const rpcprog_t, const rpcvers_t,
 			 const struct netconfig *);
-extern rpcblist	*rpcb_getmaps(const struct netconfig *, const char *);
+extern struct rpcblist	*rpcb_getmaps(const struct netconfig *, const char *);
 extern enum clnt_stat rpcb_rmtcall(const struct netconfig *,
 				   const char *, const rpcprog_t,
 				   const rpcvers_t, const rpcproc_t,

Easy fix (I don't have a commit bit anymore or I'd just check it in), but it makes me wonder if anyone is building with clang on a regular basis or they'd have caught this one quickly.

Thanks,
