[usocket-devel] ECL and MSVC

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?
