ok for those ones.

I'm quite surprised about that one. The compiler should be smart enough to see 
that in "int quad;" quad is a variable name, not a struct. Which error message 
do you get exactly ?

Can you try to compile the following test.cpp file ?

```
typedef struct _quad { int val[2]; } quad_t;    /* used by UFS */
typedef quad_t          quad;                   /* used by UFS */

struct foo
{
    int quad;
};

int main()
{
    int quad = 0;
    return quad;
}
```

$ g++ -std=c++11 test.cpp -c

Works fine on Linux. If adding, -Wshadow, it will complain though about the 
int quad = 0 shadowing the global declaration of typedef quad_t quad;

It is essentially the same as my pull request, or am I missing somethig ?

Which one do you mean by the last one, the one for io.cpp ?
