My Linux distribution is RedHat / CentOS 5.x i386/x86_64.
I'm using custom compiled Apache version 2.2.17 (both worker and prefork) modes with mod_php (PHP 5.2.17) custom compiled too.
phpinfo() page shows "Thread Safety" is 'enabled'.
My problem is latest ZendOptimizer version 3.3.9 doesn't provide thread safe extensions (_ts.so) anymore. So it is required to disable "Thread Safety" in PHP.
How can I configure (*.ini options) or compiling (configure options, make flags, etc.) mod_php with Thread Safety disabled
