Compile undex AIX 4.3

Hi, I'm trying to compile PHP4.0.2 on an IBM RS6K with AIX 4.3 and Apache 1.3.12, but I'm getting these errors when compiling zend, and then when I will compile Apache the "ld" app can't find these functions. The errors are: /bin/sh ../libtool --silent --mode=compile cc -DHAVE_CONFIG_H -I. -I. -I.. -DXML_BYTE_ORDER=21 -g -c ./zend_execute.c "./zend_execute.c", line 2328.1: 1506-162 (W) No definition was found for function zend_assign_to_variable_reference. Storage class changed to extern. "./zend_execute.c", line 2328.1: 1506-162 (W) No definition was found for function zend_ptr_stack_get_arg. Storage class changed to extern. "./zend_execute.c", line 2328.1: 1506-162 (W) No definition was found for function zend_ptr_stack_clear_multiple. Storage class changed to extern. "./zend_execute.c", line 2328.1: 1506-162 (W) No definition was found for function i_zend_is_true. Storage class changed to extern. "./zend_execute.c", line 2328.1: 1506-162 (W) No definition was found for function safe_free_zval_ptr. Storage class changed to extern. There is something I can do about it?
