- rel 11; BIG FAT WARNING: we are now building php WITHOUT ZTS
(zend thread safety) as it was "for code maintainers only!!".

We were using it because we hoped that zts will be fully supported
in php but it never happened and php devs are now insisting more
and more that this option shouldn't be used in normal builds
(look at commit logs and diffs for Zend/Zend.m4 in php repository)

Changed files:
    php.spec -> 1.909
