It's not like this is going to break the common case where the user doesn't set any specific PCRE flags in configure, and I don't think it's unreasonable to expect third party packagers to use a bundled library if they're building on that old a system. They're effectively shouldering the burden of providing security updates for PHP regardless of what the distro does. Adam
