Compiling Error C3861 identifier when compiling on windows

[Mjmackan]

Hello, getting below error on several locations when compiling an untouched TFS 1.4 VC 17 with my Visual Studio 2022.
Any suggestion on how to fix these errors? It says C3861 is an identifier issue, but I haven't changed anything in the code.
