While I don't necessarily disagree with you, this removes all 
possibility of abstraction. Even a local function cannot be used to 
factor out initialization of a C resource.

I think code which does not properly do cleanup of C resources it uses, 
or does so with the expectation that the cleanup must be running after 
`main` exits is very suspect. But the fact that you can't rely on the 
recommended remedy in the spec needs fixing, and I don't think this 
fixes it.

This also introduces unnecessary storage of pointers when not necessary 
(probably the vast majority of extern(C) calls).
