Subject: bison 3.0
From: sebastian@php.net (Sebastian Bergmann)

 Hi!

 I just updated my notebook to Fedora 21 and am no longer able to
 build PHP on it since I now have bison 3.0.2 instead of bison 2.7.

 bison 3.0 is blacklisted in Zend/acinclude.m4. Is bison 3.0
 incompatible with our parser specification? If so, will it be
 upgraded? It's not really a good situation to be incompatible
 with current versions of essential tools such as bison.

 Best,
Sebastian
