Doesn't work:

address@hidden pr19579]$ cat x.c
#include <stdio.h>

int foo[1];
int bar[1];

extern int *foo_p (void);
extern int *bar_p (void);

int
main ()
{
  if (foo[0] == 0 && foo == foo_p () && bar[0] == 0 && bar == bar_p ())
    printf ("PASS\n");
  return 0;
}
address@hidden pr19579]$ cat foo.c
int foo[2];
int bar[2] = { -1, -1 };

int *
foo_p (void)
{
  return foo;
}

int *
bar_p (void)
{
  return bar;
}
address@hidden pr19579]$ make
