Compile errors on AIX 4.2.1

I'm getting errors when compiling PHP4 Beta 1: This installation is on AIX 4.2.1. Here's my do-conf (copied directly from my 3.0.11 installation): rm config.cache ./configure --with-mysql=/usr/local/lib/mysql \ --with-ldap \ --with-openlink=/usr/openlink --enable-trackvars \ --with-apache=/usr/local/lib/apache_1.3.6 This runs fine, then when I 'make', I get the following error: Making all in ext Making all in apache gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../../libzend -I../../TSRM -I/usr/ local/lib/apache_1.3.6/src/include -I/usr/local/lib/apache_1.3.6/ src/os/unix - I/usr/local/include -I/usr/local/lib/mysql/include -I -I../.. - I../../libzend -O2 -g -c apache.c In file included from /usr/local/lib/apache_1.3.6/src/include/ap_config.h:115, from ../../php.h:170, from apache.c:22: /usr/local/lib/apache_1.3.6/src/os/unix/os.h:116: conflicting types for `dlerror ' /usr/include/dlfcn.h:35: previous declaration of `dlerror' make: The error code from the last command is 1.
