Read symbolic links on windows instead of synchting a null file

[fakuivan]

How could code from:

seafile/lib/utils.c

Lines 532 to 561 in 9299751

	#ifdef WIN32
	wchar_t *wpath;
	DWORD access = 0;
	HANDLE handle;
	int fd;
	access |= GENERIC_READ;
	if (flags & (O_WRONLY | O_RDWR))
	access |= GENERIC_WRITE;
	wpath = win32_long_path (path);
	handle = CreateFileW (wpath,
	access,
	FILE_SHARE_DELETE | FILE_SHARE_READ | FILE_SHARE_WRITE,
	NULL,
	OPEN_EXISTING,
	0,
	NULL);
	if (handle == INVALID_HANDLE_VALUE) {
	errno = windows_error_to_errno (GetLastError());
	g_free (wpath);
	return -1;
	}
	fd = _open_osfhandle ((intptr_t)handle, 0);
	g_free (wpath);
	return fd;
	#else

be changed so that it reads symbolic links correctly on windows? Currently they are read as an empty file.
