In the following program...
==========
typedef struct s
{
 char *n;
};
int main()
{
 char* o;
 #define P ((struct s *) o) 
 P->n = "Jack"; //extract
 return 0;
}
==========

...if you select the statement on line 9 and invoke the Extract Function refactoring, CDT produces the following code:
==========
typedef struct s
{
 char *n;
};

void extracted_function(char* o) {
	P->n = "Jack";
}

int main()
{
 char* o;
 #define P ((struct s *) o) 
	extracted_function(o);
 return 0;
}
==========

Macro P is undefined in the extracted function.
