Functions with a this argument are not shown in outline view

Suppose I have the following struct and function prototype defined in Product.h

struct Product
{
  int a;
};

typedef struct Product Product;

extern int Product_GetA(Product* this);

Then, in Product.c

#include "Product.h"

int Product_GetA(Product* this)
{
  return this->a;
}

The function "Product_GetA" is not listed in the Code Composer v4 outline view, and this is caused by having an argument named "this". If I change the function prototype and implementation to "Product_GetA(Product* product) the function is listed. I'd argue that this should work for a C project in CCSv4?
