 Description   

MariaDB 10.4.10 occurs the following build error when build it by MSVC++.

```text
C:\projects\source\sql\item_subselect.cc(126): error C2146: syntax error: missing ')' before identifier 'or' [C:\projects\build\sql\sql.vcxproj]
```

The cause of this error to use "or" in the following code.

https://github.com/MariaDB/server/commit/b44171428ab2ea25db82f7cd27349e67812e4921#diff-002eab3ce25a9edf12c07fa4999ea6b4R126

Normally, MSVC++ can't interpret "or".
Therefore the above code is a syntax error.
