I highly doubt this is correct. I have a feeling there are all kinds of ways you can get this to fire on things that aren't a function declaration. It's also inefficient to check the identifier string every time we make a function type. Please find somewhere else to add this. I'd suggest adjusting the function type in CheckMain, or some time before then, whereever we make main implicitly extern "C".
