        <pre>Unspecified behavior: different formatting rules if there is enum declaration
directly before 'typedef enum' or 'extern'.

Configuration of clang-format.
BraceWrapping: AfterEnum is set to true. 
Code:

// BEFORE:
extern "C" {
#include <IfAaSysLog.h>
}

typedef enum { a, b, c } MyEnum;

enum SomeEnum
{
    AAA = 1,
    BBB = 2,
}

extern "C" {
#include <IfAaSysLog.h>
}

enum SomeEnum
{
    AAA = 1,
    BBB = 2,
}

typedef enum { a, b, c } MyEnum;



//AFTER:
extern "C" {
#include <IfAaSysLog.h>
}

typedef enum { a, b, c } MyEnum;

enum SomeEnum
{
    AAA = 1,
    BBB = 2,
}

extern "C"
{
#include <IfAaSysLog.h>
}

enum SomeEnum
{
    AAA = 1,
    BBB = 2,
}

typedef enum
{
    a,
