g++ 2.96 bug handling 'extern'.

[Sergei Organov]

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
