Subject: params: allow param name aliases
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1d221516cdff8e0674a097e5913c16b5ea26bedc;p=thirdparty%2Fopenssl.git

params: allow param name aliases

We allowed multiple names for the same parameter in a number of places.
This is best dealt with in the generated code.
