 Hello,

 'cc1plus' version 2.96 20000530 (experimental) still doesn't permit matching
 external declarations inside functions. Neither cc1-2.96 nor cc1plus-2.95.2
 have the problem. The diagnostic is surprising:

 extern.cc: In function `void foo ()':
 extern.cc:7: declaration of `int j'
 extern.cc:6: conflicts with previous declaration `int j'

 How to reproduce:

 osv@osv$ cat extern.cc
 extern int i;
 void foo(void)
 {
   extern int i;
   extern int i;
   extern int j;
   extern int j;
 }
 osv@osv$ ~/try/bin/ppc-eabi-g++ -c -v extern.cc
