But more importantly, I think you can do much better with the same
space. Perhaps like this.

IIRC historically the division between ssl and crypto was messy.
Especially, I am not sure if the change to NEEDS_SSL_WITH_CRYPTO
in this patch is correct for platforms that require that macro
defined.
Other changes in this patch looks sensible, though.
