When using ecl that has been built with msvc, the code in sbcl.lisp

#-:wsock

(ffi:clines

"#include <errno.h>"

"#include <sys/socket.h>")

#+:wsock

(ffi:clines

"#ifndef FD_SETSIZE"

"#define FD_SETSIZE 1024"

"#endif"

"#include <winsock2.h>")

(ffi:clines

"#include <sys/time.h>"

"#include <ecl/ecl-inl.h>"

)

Doesn't build because sys/time is not available in msvc. What header should I include instead?
