Lines 222-224 of f77-fcn.c are

  extern CRUFT_API F77_RET_T
  F77_FUNC (xstopx, XSTOPX) (F77_CONST_CHAR_ARG_DECL
                             F77_CHAR_ARG_LEN_DECL) GCC_ATTR_NORETURN;

and lines 42-65 of f77-fcn.c are

  F77_RET_T
  #if defined (F77_USES_CRAY_CALLING_CONVENTION)
  F77_FUNC (xstopx, XSTOPX) (octave_cray_ftn_ch_dsc desc)
  #elif defined (F77_USES_VISUAL_FORTRAN_CALLING_CONVENTION)
  F77_FUNC (xstopx, XSTOPX) (const char *s, int slen)
  #else
  F77_FUNC (xstopx, XSTOPX) (const char *s, long slen)
  #endif
  {
  #if defined (F77_USES_CRAY_CALLING_CONVENTION)
    const char *s = desc.const_ptr = ptr_arg;
    unsigned long slen = desc.mask.len;
  #endif

    f77_exception_encountered = 1;

    /* Skip printing message if it is just a single blank character.  */
    if (s && slen > 0 && ! (slen == 1 && *s == ' '))
      (*current_liboctave_error_handler) ("%.*s", slen, s);

    octave_jump_to_enclosing_context ();

    F77_RETURN (0)
  }

F77_FUNC should be defined in your config.h file.  Is it?  If not, you
need to determine why it was not defined correctly for your system.
