gcc function auto-prototyping don't work?

Hi!
have two .ino
first :

```
void somefunction()
{
}
setup()
{
}
loop()
{
somefunction();
}
```

and second:

```
setup()
{
}
loop()
{
somefunction();
}
void somefunction()
{
}
```

first work ok, but second no ( error: 'somefunction' was not declared in this scope) if used latest ide from git...
but some time ago (i think ~1.6.5 version did work)...
