an issue with the tracking header file

[huye]

Type: Bug

After upgrading VSCode to 1.93, some types in the code appear as undefined or have type errors.

I don't know if it's because the extension was automatically updated. I have now reduced the expansion to 1.21.6 and it will be normal.

My current version is normal, the problematic version is after 1.22.

I don't know if there is a problem with the path processing of system header files.

The following are examples of errors:

note: I have correctly included the header files and can compile and run normally.

typedef uint64_t myint;
When the mouse is placed on it, it prompts:

identifier "uint64_t" is undefined

myint myvar;
Same as above:

typedef <error-type> myint

@huye 1.22.x changed the behavior of the recursive includes feature that is used if "**" is at the end of an includePath, which is the default, e.g. ${workspaceFolder}/** (#11485). If your root recursive include path contains any file with the same name as a system include path then it'll be used instead of the system include path. You can run the C/C++: Log Diagnostics command after opening a source file to see the list of include paths that are generated by the "**". If you can add the include paths with system headers to C_Cpp.files.exclude then it could cause the system headers to be used instead.

The header file settings remain the same before and after the upgrade. The system header file path is the default value.
