Unable to install php 5.2.1 on apache 2.2.0 (solaris 10)

Hi, We have an existing apache 2.2.0 instance on Soalris. I am trying to compile php 5 support into it. We need to use the sun studio8 cc compiler as the same was used for apache 2.2.0. On running make, it errors out with the following error: /opt/swt/source/build/php-5.2.1/sapi/apache2handler/apache_config.c", line 181,183 etc ... with: syntax error before or at: . those lines are: AP_INIT_TAKE2("php_value", php_apache_value_handler, NULL, OR_OP TIONS, "PHP Value Modifier"), 182 AP_INIT_TAKE2("php_flag", php_apache_flag_handler, NULL, OR_OPTI ONS, "PHP Flag Modifier"), 183 AP_INIT_TAKE2("php_admin_value", php_apache_admin_value_handler, NULL, ACCESS_CONF|RSRC_CONF, "PHP Value Modifier (Admin)"), 184 AP_INIT_TAKE2("php_admin_flag", php_apache_admin_flag_handler, N ULL, ACCESS_CONF|RSRC_CONF, "PHP Flag Modifier (Admin)"), 185 AP_INIT_TAKE1("PHPINIDir", php_apache_phpini_set, NULL, RSRC_CON F, "Directory containing the php.ini file"), 186 {NULL} does anyone know how to resolve this ...
