For input file `test.c`:
```c
#include <stdio.h>
#ifndef MSG
#define MSG "hello world"
#endif
void hello() {
printf(MSG);
}
```
and `compile_commands.json`:
```json
[
{
"directory": "/tmp",
"command": "clang -UMSG -c -o test.o test.c'",
"file": "test.c",
"output": "test.o"
}
]
```
clangd reports false positive:
```console
$ clangd --check=test.c
