Just let me note that "--enable-nonfree" is an incredibly poor and
confusing name choice (what is "free"?, why should a non-GPL license
be considered "non-free"?). Thus it is almost inevitable that it will
"free" is a vastly generic term and should not be used in technical
context. A possibly better choice would be "--enable-non-rms-free".
