  We have a DECstation3100 running Ultrix/3.1.  The following code
cause an error.  Is this bug already fixed?


/*------------------------------*/
seraph:2 cat > a.c
typedef int* IPTR;
int tako(int x, int y) {
  extern int ika(IPTR, IPTR);
  return(ika(&x, &y));
}
seraph:3 cc -c a.c
ccom: Error: a.c, line 3: syntax error
        extern int ika(IPTR, IPTR);
      --------------------------^
ccom: Error: a.c, line 3: function declaration in bad context
        extern int ika(IPTR, IPTR);
      ---------------------------^
ccom: Error: a.c, line 4: illegal function
        return(ika(&x, &y));
      -------------------^

        return(ika(&x, &y));
