- see ftp://ftp.csx.cam.ac.uk/pub/software/email/exim/ChangeLogs/ChangeLog-4.22
- IPv6 bug (src/os.c) fix included, patch removed
- hacked around with mutating OS/Makefile-FreeBSD and src/EDITME

- used new INFO macro
- used PATCHFILES instead of patching by hand, now that exiscan without ACL is gone
