<pre>This bug report captures what Richard Smith wrote in a code review message
(<a href="http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20150608/130447.html">http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20150608/130447.html</a>):
<span class="quote">> We should also filter out internal-linkage declarations and non-TU-scope
> declarations when we perform the deferred handling of
> `ExtnameUndeclaredIdentifiers` in `ActOnVariableDeclarator` and
> `ActOnFunctionDeclarator`.</span >
...
<span class="quote">> Here's a trivial testcase (it's easy to cook up more, the</span >
bug is quite blatant):
<span class="quote">>
> #pragma redefine_extname foo bar
> int f() {
> int foo = 0;
> return foo;
> }
> int foo() { return 1; }
>
> The redefine_extname gets applied to the local variable 'foo', and the
> global function 'foo' does not get renamed.</span >
