I think this is a bad idea. If you have an extern typedef int, how  
often do you really know what it is? On all platforms? With all c  
configuration options and into the future? Nearly every typedef int  
would have to be unranked, which would be a pain to code with.

I'm not against the unranked/partially ordered types--it's a good  
one, but think it will be burdensome (as well as hugely backwards  
incompatible) to make it the default. (We should document the issues  
that may arise in the users manual though.)
