Dear PHP/Zend folks :
This is a bug I think. I recently saw that PHP had been updated to 5.4.10
and I
decided to update my php bits in /usr/local. I was quite surprised to see in the
configure output this warning about bison :
checking for bison... bison -y
checking for bison version... invalid
configure: WARNING: bison versions supported for regeneration of the Zend/PHP
parsers: 1.28 1.35 1.75 1.875 2.0 2.1 2.2 2.3 2.4 2.4.1 2.4.2 2.4.3 2.5 2.5.1
2.6 2.6.1 2.6.2 (found: 2.6.5).
This seems odd to me as bison 2.6.5 builds and tests perfectly on my
Solaris 10
server and so therefore I wonder what these PHP folks are on about? Is this a
"Warning"
or a real configure fault? If the latter then I need to backout bison in order
to build
PHP and then re-install a perfectly functional bison ?

Unless you are hacking PHP you can ignore Bison. Check the Makefile
for where it is used. The PHP distribution contains
Zend/zend_language_parser.[ch] and php-5.5/Zend/zend_ini_parser.[ch]
already built from their respective .y files so bison is not
generally invoked when building PHP.
Of course, if 2.6.5 is verified than it should be added to
bison_version_list in Zend/acinclude.m4. Feel free to regenerate the
parsers with it, review the test suite results, and create a github
pull request.
