Summary: fatal internal error w/ZendEngine2

Initial Comment:
a user reported this via the Gentoo bugzilla ... when
trying to build the ZendEngine2 in php cvs, flex dies:

wget
'http://cvs.php.net/viewcvs.cgi/checkout/ZendEngine2/flex.skl'
wget
'http://cvs.php.net/viewcvs.cgi/checkout/ZendEngine2/./zend_language_scanner.l'
flex -Pzend -S./flex.skl -ozend_language_scanner.c
-i ./zend_language_scanner.l
flex: fatal internal error, bad line in skeleton file

looks like it's due to the usage of '%*', '%+', and
'%-' in the flex.skl file, but i'm not lex expert and
i'm just guessing at this point :)

They appear to be using a custom skeleton. The skeleton has
changed significantly since past releases.

If they really need their own skeleton, I suggest they
create a patch between the flex 2.5.4 skeleton and their own
skeleton to identify the differences. Then, using that patch
merely as a guide, patch the 2.5.33 skeleton BY HAND to
upgrade it. However, I suspect they don't really need the
custom skeleton.

Please have someone from the Zend team contact me directly
so I can help them refactor their code to use flex 2.5.33.
