compile error

I'm trying to compile PHP 4.2.2. I am running Apache 2.0.40 (yes I know support is experimental). I am compiling on Redhat 7.3 Linux 2.4.18. I did my PHP configure line: ./configure --enable-track-vars --with-mysql --with-mail --with-apxs2=/usr/local/apache2/bin/apxs and then I do a make, and it errors out with: make[3]: Entering directory `/root/php-4.2.2/sapi/apache2filter' /bin/sh /root/php-4.2.2/libtool --silent --mode=compile gcc -I. -I/root/php-4.2.2/sapi/apache2filter -I/root/php-4.2.2/main -I/root/php-4.2.2 -I/usr/local/apache2/include -I/root/php-4.2.2/Zend -I/root/php-4.2.2/ext/mysql/libmysql -I/root/php-4.2.2/ext/xml/expat -D_REENTRANT -I/root/php-4.2.2/TSRM -DTHREAD=1 -g -O2 -pthread -DZTS -prefer-pic -c sapi_apache2.c sapi_apache2.c: In function `php_register_hook': sapi_apache2.c:534: warning: passing arg 3 of `ap_register_output_filter' makes pointer from integer without a cast sapi_apache2.c:534: too few arguments to function `ap_register_output_filter' sapi_apache2.c:535: warning: passing arg 3 of `ap_register_input_filter' makes pointer from integer without a cast sapi_apache2.c:535: too few arguments to function `ap_register_input_filter' make[3]: *** [sapi_apache2.lo] Error 1 make[3]: Leaving directory `/root/php-4.2.2/sapi/apache2filter' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/root/php-4.2.2/sapi/apache2filter' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/php-4.2.2/sapi' make: *** [all-recursive] Error 1 Has anyone else had similar errors and found a solution?
