D2 is really that stable as it is claimed to be?

I've reduced the code causing the error to this:
```
public enum GTokenType
{
	NONE,
}

public enum GtkRcTokenType
{
	INVALID = GTokenType.NONE,
	INCLUDE,
}
```

In this case the value of INVALID + 1 isn't large enough the overflow an 
int.

In the actual code:
https://github.com/gtkd-developers/GtkD/blob/master/src/gtkc/glibtypes.d#L1310
Setting NONE to a value lower than 87 makes it so the code compiles 
without error, which only makes things weirder.
