 Starting in Visual Studio 2019 version 16.6, the compiler implements some preexisting C++ warnings for code compiled as C. The following warnings are now enabled at different levels: C4060, C4061, C4062, C4063, C4064, C4065, C4808, and C4809. Warnings C4065 and C4060 are disabled by default in C.
 
-The warnings trigger on missing **`case`** statements, undefined **`enum`**, and bad **`bool`** switches, that is, ones that contain too many cases. For example:

 The same restrictions are applied recursively to each nested class. The restriction is meant to ensure the simplicity of structs that have `typedef` names for linkage purposes. They must be simple enough that no linkage calculations are necessary before the compiler gets to the `typedef` name for linkage.
