It is hard to judge what "widely supported" means. PHP is so widespread that people run it on embedded systems, 10+ year old servers (see old masters.php.net) and compile them with compiler most of us have never touched (suncc, pcc). I think we have to come up with good arguments for C99 support that we just can't do with C89 in order to potentially keep out people. tl;dr: I believe unless we have strong arguments we should acknowkledge that PHP is so widespread that changing compiler can make some users unhappy and if we don't have really good reasons we shouldn't. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
