X-Macro expansion false error.

Environment

• OS and Version: Debian GNU/Linux 13 Trixie
• VS Code Version: 1.119.0
• C/C++ Extension Version: 1.32.2

Bug Summary and Steps to Reproduce

Bug Summary:
False error with X-Macros.

Steps to reproduce:

1. Create a new C file colors.def for example with this content :

COLOR(RED)
COLOR(GREEN)
COLOR(BLUE)

3. Create another C file like main.c with this content :

enum colors_t {
#define COLOR(NAME) NAME,
#include "colors.def"
#undef COLOR
};

4. See the false error "expected an identifier" but compilation works perfectly.

Expected behavior:
No false error as the macro should expand and complete the enum.

Configuration and Logs

}

Other Extensions

Issue still persist after disabling any other extensions.

Additional context

This is not a fatal error since it is only visual but it is a problem in intellisense that shows up error even if there are not...

Riproduci la diagnostica con i due file nominati nel report, colors.def e main.c, usando il pattern X-macro mostrato. Traccia il modo in cui IntelliSense analizza l’espansione della macro inclusa e identifica perché segnala “expected an identifier”; il lavoro è completato quando la diagnostica falsa scompare mentre l’esempio continua a essere compilato correttamente.
