This testcase should work for powerpc-apple-darwin9...

----------------------------------------------------
#include "unwind.h"

int
main()
{
  struct _Unwind_Context *context;
  int ip_before_insn = 0;  

   return _Unwind_GetIPInfo (context, &ip_before_insn); 
}
----------------------------------------------------
It produces...

$ gcc -Werror-implicit-function-declaration  -c test.c
test.c: In function 'main':
test.c:9: error: implicit declaration of function '_Unwind_GetIPInfo'

and

$ gcc-4.2 -Werror-implicit-function-declaration  -c test.c
$
