HELP: Unable to get PHP 3 or 4 compiled

I am trying to get PHP compiled on SuSE 6.3 (Linux) to run as a loadable module on Apache 1.3.12. I am getting the same error on PHP 4.0.1p12 and 3.0.16. The 4.0.1p12 error looks like this: make[3]: Entering directory `/usr/src/php-4.0.1pl2/ext/standard' /bin/sh /usr/src/php-4.0.1pl2/libtool --silent --mode=compile gcc -DHAVE_CONFIG_H -I. -I/usr/src/php-4.0.1pl2/ext/standard -I/usr/src/php-4.0.1pl2 -I/usr/src/php-4.0.1pl2/main -I/data01/ci-dev/include/apache -I/usr/src/php-4.0.1pl2/Zend -I/usr/src/php-4.0.1pl2 -I/data01/home/db2inst1/sqllib/include -I/usr/src/php-4.0.1pl2/ext/xml/expat/xmltok -I/usr/src/php-4.0.1pl2/ext/xml/expat/xmlparse -DXML_BYTE_ORDER=12 -g -O2 -c microtime.c microtime.c: In function `php_if_getrusage': microtime.c:97: storage size of `usg' isn't known microtime.c:100: `RUSAGE_SELF' undeclared (first use in this function) microtime.c:100: (Each undeclared identifier is reported only once microtime.c:100: for each function it appears in.) microtime.c:106: `RUSAGE_CHILDREN' undeclared (first use in this function) If you have any ideas, please pass them along.
