Seems Windows defines sockaddr_in6 in ws2tcpip.h. Something like this
should get the compile working a bit further:

diff --git a/erts/epmd/src/epmd_int.h b/erts/epmd/src/epmd_int.h
index 14d05c3..ae7cbcb 100644
--- a/erts/epmd/src/epmd_int.h
+++ b/erts/epmd/src/epmd_int.h
@@ -49,6 +49,7 @@
 #  ifndef WINDOWS_H_INCLUDES_WINSOCK2_H
 #    include <winsock2.h>
 #  endif
+#  include <ws2tcpip.h>
 #  include <windows.h>
 #  include <process.h>
 #endif

I'll regenerate the patch. Sorry for the problem! No windows systems to
test with here.
