Yes.  Split the file in two.

Why on earth would you want to do something to completely frustrate the
next person that looks at your code?  There's no reason to "unscope" a
variable; if that's what you want, use the perfectly good mechanism of
splitting the file and making the variable have file scope (i.e., not 
extern).

I mean, there may *be* a way to do this, but you really shouldn't want to.
Honest.
