+Description:
+
+Adds pcre2 support. Prefers pcre2 over pcre if both are available.
+
+
+Config changes:
+
+None
+
+
+Upgrade instructions:
+
+Cyrus will prefer pcre2 over pcre if both are installed. If you have both
+installed and wish to use pcre rather than pcre2, run configure with
+--disable-pcre2.
+
+If you haven't specifically installed libpcre2-dev (or whatever your system's
+equivalent is), you might still have parts of pcre2 installed due to other
+packages on your system depending on it. This can confuse configure into
+thinking you have a usable pcre2 when you don't. Either properly install
+libpcre2-dev so Cyrus can use it, or configure Cyrus with --disable-pcre2
+so that it ignores the partial installation.
+
+Please note that on Debian-based systems, pcre (the old one, no longer
+maintained) is called "pcre3". Yes, this is confusing.

Subject: [PATCH 2/4] sieve/sieve.y: fix pcre2 crash when regex_t uninitialised
Fixes crash when trying to regfree() after regcomp() failure
Seems like this usage was fine with the old pcreposix, but is a
problem with pcre2posix.
