Well, after trying, unsuccessfully, to run the tests that come with the
crm114 tarball, I decided not to even try to filter mail with it.
Anyway, I think a port should include some kind of warning about
memory requirements. I mean, IIRC the thing defaults to something
like 4 x 24MB filter files in memory, and the minimum is something
like 4 x 8MB or something like that.

Hey, that's not so bad. I don't how well it would work with every
user filtering their mail with it, but those numbers certainly put it
as a decent personal mail fiter.
Also, wasn't there something with wchar.h so libtre doesn't support
unicode and thus crm114 doesn't filter unicode messages, or something?
