Subject: Re: [PHP-DEV] PHP 5.2 - No easy installation for users anymore?
From: nlopess@php.net ("Nuno Lopes")

Hi,

Currently we have to bail out if a new flex is installed, because the new 
flex versions simply die when parsing the flex skeleton bundled in the Zend 
folder. Why this happens? because flex has suffered a lot of changes and 
doesn't support the old skeletons.

So currently we are stuck with the old flex version. This problem is so 
irritating to me, that I even have that in my TODO list. The new flex 
already supports re-entrant parsers, so we could get rid of the bundled 
skeleton plus all the engine hacks related with flex.

Nuno
