#pragma redefine_extname and local declarations

[Mark Mitchell]

Joseph, Zack --

Given:

  #pragma redefine_extname f g

  int main () {
    extern int f();
    f();
  }

we do not rename "f" to "g".  Perhaps even more dramatic is the case 
where there is no declaration of "f" at all; because that results in an 
implicit local declarations we get the same behavior.

This did not work in GCC 3.4 either, so I don't think it had anything to 
do with Zack's changes to redefine_extname in GCC 4.0.  But, I'd be 
curious as to whether or not you think that this behavior is as 
desired.  If you don't think this is the desired behavior, then perhaps 
we should be calling maybe_apply_renaming_pragma more often -- after 
every function declaration with external linkage in finish_decl, rather 
than just those with global scope.

Thoughts?
