`XtOffsetOf' redefined messing up 4.1.2 build

I'm trying to build PHP 4.1.2 with an existing static Apache 1.3.23 installation, and am having some resolution problems I haven't seen before. This is on a dusty old Free BSD 2.2.2 system, but I was able to build 4.1.1 with no problems with the same configuration. It uses gcc version 2.7.2.1 --- yes, I know I should upgrade the OS, but since it was able to make 4.1.1 ok a few weeks ago, I'm guessing that isn't the problem. I'm compiling in postgres and gd support, but have the same problem with them out. I followed the steps (minimal apache, php, fuill apache), running configure each time and doing a make clean. During the PHP make I see: gcc -I. -I/usr/local/src/php-4.1.2/sapi/apache -I/usr/local/src/php-4.1.2/main -I/usr/local/src/php-4.1.2 -I/usr/local/src/apache_1.3.23/src/include -I/usr/local/src/apache_1.3.23/src/os/unix -I/usr/local/src/php-4.1.2/Zend -I/usr/local/src/php-4.1.2/ext/xml/expat -I/usr/local/src/apache_1.3.23/src/include -I/usr/local/src/apache_1.3.23/src/os/unix -I/usr/local/src/php-4.1.2/TSRM -g -O2 -c mod_php4.c && touch mod_php4.lo In file included from /usr/local/src/apache_1.3.23/src/include/httpd.h:72,

I tried an Apache build, but it gave me: ===> src/modules/php4 gcc -c -I../../os/unix -I../../include -funsigned-char -I/usr/local/src/php-4.1.2 -I/usr/local/src/php-4.1.2/main -I/usr/local/src/php-4.1.2/main -I/usr/local/src/php-4.1.2/Zend -I/usr/local/src/php-4.1.2/Zend -I/usr/local/src/php-4.1.2/TSRM -I/usr/local/src/php-4.1.2/TSRM -I/usr/local/src/php-4.1.2 -DUSE_EXPAT -I../../lib/expat-lite ../../apaci -fpic -DSHARED_MODULE mod_php4.c && mv mod_php4.o mod_php4.so-o In file included from ../../include/httpd.h:72,
