Solaris 9, Apache 2.044, PHP 4.3.1 - too few arguments ti function 'readdir_r'

I am attempting to upgrade to the latest version of Apache and PHP on a Solaris 9 server and have the following error. (I searched the web and found many cases of this error but no solutions.) All of the software has been updated to the latest versions (gcc make .....) /bin/sh libtool --silent --mode=compile gcc -Imain/ -I/export/home/jjohnson/apache-2.0.44-install/php-4.3.1/main/ - DPHP_ATOM_INC -I/export/home/jjohnson/apache-2.0.44-install/php-4.3.1/includ e -I/export/home/jjohnson/apache-2.0.44-install/php-4.3.1/main -I/export/hom e/jjohnson/apache-2.0.44-install/php-4.3.1 -I/usr/local/apache-2.0.44/includ e -I/export/home/jjohnson/apache-2.0.44-install/php-4.3.1/Zend -I/usr/local/ mysql/include -I/export/home/jjohnson/apache-2.0.44-install/php-4.3.1/ext/xm l/expat -D_POSIX_PTHREAD_SEMANTICS -I/export/home/jjohnson/apache-2.0.44-in stall/php-4.3.1/TSRM -g -O2 -prefer-pic -c /export/home/jjohnson/apache-2.0.44-install/php-4.3.1/main/reentrancy.c -o main/reentrancy.lo /export/home/jjohnson/apache-2.0.44-install/php-4.3.1/main/reentrancy.c: In function `php_readdir_r': /export/home/jjohnson/apache-2.0.44-install/php-4.3.1/main/reentrancy.c:106: too few arguments to function `readdir_r' make: *** [main/reentrancy.lo] Error 1 gcc -v Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.9/3.2.2/specs Configured with: ../configure --disable-nls --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/ as Thread model: posix gcc version 3.2.2 make -v GNU Make 3.80 Copyright (C) 2002 Free Software Foundation, Inc.
