My read of

	"no-comp 	Disables compression independent of zlib. OPENSSL_NO_COMP 
will be defined in the OpenSSL headers."

is that this disables compression methods OTHER than zlib.

Is the intent, instead, that it disables ALL compression, REGARDLESS of 
the presence/setting of zlib?

Ah, I see the diffs in the 1.0.2 -> 1.1.0 changelog at
