PHP 4.3.3 compile error

Hello, I'm trying to compile PHP 4.3.3. My configure is: ./configure --enable-track-vars --without-mysql --with-mail --with-apxs2=/usr/local/apache2/bin/apxs --with-informix and when doing make I get: [root@archivesnew php-4.3.3]# make /bin/sh /root/php-4.3.3/libtool --silent --preserve-dup-deps --mode=compile gcc -I/usr/informix/incl/esql -Iext/informix/ -I/root/php-4.3.3/ext/informix/ -DPHP_ATOM_INC -I/root/php-4.3.3/include -I/root/php-4.3.3/main -I/root/php-4.3.3 -I/root/php-4.3.3/Zend -I/root/php-4.3.3/ext/xml/expat -I/root/php-4.3.3/TSRM -g -O2 -prefer-pic -c /root/php-4.3.3/ext/informix/ifx.c -o ext/informix/ifx.lo /root/php-4.3.3/ext/informix/ifx.ec: In function `zm_info_ifx': /root/php-4.3.3/ext/informix/ifx.ec:402: parse error before '/' token /root/php-4.3.3/ext/informix/ifx.ec:3127:17: operator '<' has no left operand make: *** [ext/informix/ifx.lo] Error 1 I'm not a programmer, so any advice on why its breaking on making the informix code and how to fix it would be appreciated. Thanks! Adam
