>Description:

        OpenSSL supports the use of zlib to compress data transmitted
        over TLS sessions, but it is disabled by default.  Since zlib
        is available nearly everywhere, including the NetBSD base
        system, it is probably sensible to enable this by default (and
        it would be convenient if enabled in the NetBSD base system's
        OpenSSL, too).  At the very least, it would be nice to have as
        an option when building OpenSSL.

>How-To-Repeat:
>Fix:

        Add `zlib' to CONFIGURE_ARGS, perhaps only if a new option,
        say, `openssl-zlib', is selected.
