Code analysis reports issue with macro __has_include__ even though g++/clang++ don't complain

Bug type: Language Service

Describe the bug

• OS and Version: Windows 11
• VS Code Version: 1.69.1
• C/C++ Extension Version: 1.10.8
• Other extensions you installed (and if the issue persists after disabling them):
• If using SSH remote, specify OS of remote machine:
• A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc).

Steps to reproduce

1. open project in attached file
2. open has_include,cpp
3. press ctrl+shift+p
4. select 'C/C++: run analysis on active file'
5. see error reported:
   [{
   "resource": "/home/nick/has_include/has_include.cpp",
   "owner": "clang-tidy",
   "code": "clang-diagnostic-error",
   "severity": 8,
   "message": "function-like macro 'has_include' is not defined",
   "source": "C/C++",
   "startLineNumber": 3,
   "startColumn": 5,
   "endLineNumber": 3,
   "endColumn": 18
   }]

Expected behavior

The code analysis should not report this as the code compiles cleanly with g++/clang++.

Code sample and logs

• Code sample

See attached .tar.gz for project containing source and settings to repro. It's run on WSL Ubuntu 20.04.

• Configurations in c_cpp_properties.json

• Logs from running C/C++: Log Diagnostics from the VS Code command palette

• Logs from the language server logging

got same issues with
vscode 1.69.1, cpptooles v1.10.8
at every single class definion cpp file, the file line to include it's header file, it complained "
Error while processing C/C++(clang-diagnostic-error)[Ln1,Col1]
statx.h[Ln30,Col 6]: function-line macro' has_include' is not defined

"

The issue repros with gcc 9, but not 10. It's caused by the macro -D__has_include(STR)=__has_include__(STR) which clang (or gcc 10+) isn't able to process, but gcc 9 is. We can fix it by filtering that out (which we were already doing for IntelliSense processing as well).

Fixed with 1.11.3 (pre-release): https://github.com/microsoft/vscode-cpptools/releases/tag/v1.11.3
