Okay.

It mentions the MIT license, so I used "license:expat".  I don't think
the X11 license is meant, because the MIT license declaration on
https://github.com/JuliaLang/openlibm/blob/master/LICENSE.md does not
include the advertisement clause.

The list does miss license:public-domain, however.  Please correct me if
you think my understanding is incorrect.

Okay.

Attached is an updated patch.
