g++ 1.34.1 rejects a program that seems to me (and cfront)
valid.

Script started on Sat Apr  1 18:37:17 1989
jclark% cat same.c
struct node;

typedef int (*PCOMP)(node *, node *);

struct node {
  virtual PCOMP same_function();
};

struct dnode : node {
  PCOMP same_function();
  friend int same_dnode(dnode *, dnode *);
};

PCOMP dnode::same_function()
{
  return PCOMP(same_dnode);
}
