# 20210925 bkw: BUILD=4
# - get rid of unneeded configure lcrypto patches.
# - add bugfix patches from Debian.
# - don't install useless INSTALL in doc dir.
# - fix compiler warnings caused by such brain damage as:
#   char *foo = (char)NULL;
# - install ssmptd.conf.new and (comment-only) revaliases.new.
# - *don't* install generate_config script.
# - fix doinst.sh.

# 20200129 bkw: take over maintenance, no script changes yet.
