Subject: Re: [PHP-DEV] PHP 5.4.10 can not build Zend/PHP parsers with bison
 2.6.5

Well, the configure output claims that something is wrong, therefore the build can not be trusted. 
I'm just following the defacto way to build PHP and if the configure output claims 
something is wrong .. then it is wrong by definition.

configure claims otherwise.

do what ?  I access the release source tarball only. 

gcc-spec_node002 $ digest -a sha1 /usr/local/src/php-5.4.10.tar.gz

That is the only php sources I am allowed to use. Anything else is not "release" and 
therefore not to be used on prod servers.

Well bison 2.6.5 passes all of its own tests and therefore seems to be "okay for prod". 

I would think that a PHP release would build more or less out of the box without any
changes to the source tarball.  If PHP can not be built from the release tarball with
the typical GNU toolchain then .. it can't be built.  I just tick off a box on the build
sheet here as "does not build in compliance with defacto standard rules" and it goes
back onto the "update at some point" pile.

ps: typical GNU tools like : 

gcc-spec_node002 $ which bison 
/usr/local/bin/bison
gcc-spec_node002 $ bison --version 
bison (GNU Bison) 2.6.5
