Which of the sys/XXX.h are you looking for ?
$ cygcheck -l mingw64-x86_64-headers | grep "/sys/"
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sec_api/sys/timeb_s.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/cdefs.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/fcntl.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/file.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/locking.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/param.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/stat.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/time.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/timeb.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/types.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/unistd.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/sys/utime.h
for what I know the Windows program use winsock2.h and winsock.h
for their own socket interface
$ cygcheck -l mingw64-x86_64-headers | grep "sock"
/usr/x86_64-w64-mingw32/sys-root/mingw/include/hvsocket.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/mswsock.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/psdk_inc/_socket_types.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/winsock.h
/usr/x86_64-w64-mingw32/sys-root/mingw/include/winsock2.h
