CentOS/RHEL 5 provides libpcre 6.6, which is probably where that specific minimum version comes from. Someone out there is probably still building packages that rely on this. > I'm asking because of bug #70232 which can easily be fixed, but that > requires PCRE 8.00 (2009-10-19).

I guess the question's really whether we should still support an _external_ libpcre that old, since we bundle much newer versions. I think the argument against changing it has always been that it works and we didn't need anything newer, but if we have a reason now then that doesn't really hold. One problem is that I don't think we can really change the minimum requirement on a stable branch, so for 5.5 and 5.6 we're going to have to implement something that works with older versions regardless, but I'd be for bumping the minimum version requirement for 7.0 if it makes the code cleaner (on that branch, at least) moving forward.
