Just get rid of --with-regex=system in php configure line.

Sorry - problem source file was sapi/apache2handler/sapi_apache2.c.

I filed this as a new bug as it seems unique to the combo of PHP 4.3.2 and Apache 2.0.46 - I didn't have a problem with Apache 2.0.45 and PHP 4.3.1 and in fact just build 4.3.1 with Apache 2.0.46 and had neither the compile or runtime error.

The runtime errors follow - they come from the login page of phpMyAdmin 2.5.1-rc1, there are a number of constructs like:

// Whether the os php is running on is windows or not
if (!defined('PMA_IS_WINDOWS')) {
    if (defined('PHP_OS') && eregi('win', PHP_OS)) {
        define('PMA_IS_WINDOWS', 1);
    } else {
        define('PMA_IS_WINDOWS', 0);
    }
}

It seems like every eregi() gets the error.

Removing the --with-regex=system solved the problem - Thanks.

Closing as problem solved.

Bogusing as this was not PHP bug.
