I originally built a cut-down version of PCRE into Exim because PCRE was
new and not widely available. This has now changed; quite a lot of
OS/distributions include it. In the very long term, perhaps Exim should
be changed to use a standarly installed version of PCRE.
I do *not* want to propose that at this time (especially not for a
'point release'). However, there is a halfway stage. Exim has always
included a copy of the PCRE testing program, pcretest, which gets built
alongside Exim. I suspect that very few people discover and use this
version. As part of installing PCRE 6.0[*] into Exim, it would make
things easier to drop pcretest from the Exim distribution, and simply
include the bare minimum that Exim needs.
Any objections?

-----------------------
[*] The source files have been rearranged, and are more numerous in PCRE
6.0. Several could be omitted if pcretest isn't being built.
