Error__GLIBC_USE' is not defined when compiling cpp (IEP-1295)

[DigKleppe]

An (editor) error is generated at line:
#include "freertos/FreeRTOS.h

In included file: function-like macro '__GLIBC_USE' is not defined
/usr/include/limits.h:145:5:
note: error occurred here

This happens with .cpp files. c files OK.
The code builds OK.
I am using Espressif IDE 3.0.0 Build id: 20240605-1941, IDF 5.1.4

I removed version 3 of the plugin and installed version 2.12 manually with the LSP preview enabled.
Works OK. I can use the LSP editor here without problems. Unfortunately i have to do this every time i open a file.
The default editor setting preference does nothing.

To reproduce: add a .cpp file to hello_world example with the include.
