As far as I can see, the global variable is only used for communication 
between the two functions, of which one is a callback.
By nesting the function, the variable can be local.

The only alternative I see is to rewrite that part entirely.
Unless the gcc maintainers plan to kill this extension, I see no reason 
not to use it.
