CCing Mike as he was the author who originally added 3.0 to the exclude
list.
I have a vague memory of building master successfully with bison 3.0.2
(from homebrew) on Mac Mavericks via removing 3.0 from
bison_version_exclude in Zend/acinclude.m4 so I think that not all versions
of bison 3.0 are affected, but currently I'm using the bison27
alternative(as XCode/Command Line Tools comes with bison 2.3 by default and
master requires >=3D2.4).
