BUG: function pointer as struct member does not compile if name is same as the struct

[Maurizio Cimadamore]

Hi,
I can reproduce even with explicit struct name:

```
struct Foo {
     int (*Foo)();
};
```

I'll leave this to Sundar - my feeling is that the code in Output helper 
that handles function pointers does not check for clashes with the 
surrounding scope; we perform such checks when nesting structs inside 
other structs, but apparently the name clash logic is missing for 
function pointers.
