Hi! ext/intl presently requires ICU ≥ 4.0 (ICU 4.0 has been released on 2008-07-02[1]). Since ICU is still under vivid development our code is full of version checks (grep for ICU_VERSION), very old ICU versions are unlikely to be still around widespreadly, and we're generally not doing us a favor in supporting such old ICU versions (many PHPTs have multiple variants for different ICU versions). Therefore I have submitted PR #3487[2] which would raise the requirements to ICU ≥ 4.6 (ICU 4.6 has been released on 2010-12-02[3]).
Anatol suggested to consider to lift the requirements even to ICU ≥ 50 (ICU 50.1 has been released on 2012-11-05[4]), or maybe even to ICU ≥ 52 (ICU 52.1 has been released on 2013-10-09[5]). What do you think? Does this require an RFC?
