title: Updating PHP with custom configuration options
body: <p>Let's suppose i have built php with <code>./configure --enable-safe-mode --disable-cgi</code> etc. Is it possible to update php without loosing current configuration options? I know i could save them into a text file and bla bla but i am interesting in modifying php source files so i could <strong>compile ONLY php modules that i need</strong>. (eg. I don't need gd, tar, pgsql, mcrypt - functions that i'll <em>never</em> use. Why should i compile them?)</p>
