compile php 4.3.2
It is documented already :-)
Due to bugs in Fast CGI interface of PHP 4.3.2, it has to be configured with additional option --enable-discard-path, please disregard what is said about this option in its README.FastCGI.
And 4.3.2 does not populate path info correctly, so we still recommend 4.3.1.
We already submit bug reports to php.org.
