Fixes #9.

Hey @sunfishcode.

Hate to ask on ETA but rust-lang/rust#63806 is waiting on relicensed version of wasi or adding wasi to the exception list.

If you want more time it's fine, just let me know so I'll split libc update from that PR (to fix bug).

[mati865]

Thank you for merging it. Do you mind publishing new release on crates.io?

[sunfishcode]

cargo publish is failing, with this message:

error: api errors (status 200 OK): unknown license or other term: (Apache-2.0; see http://opensource.org/licenses for options, and http://spdx.org/licenses/ for their identifiers

At first glance, this looks like a bug in cargo, because "Apache-2.0" is a valid license identifier. Anyone have any ideas?

[mati865]

No idea, maybe it doesn't like ( before license, I'll check the code soon.

[sunfishcode]

Looks like it indeed doesn't like (: ehuss/license-exprs#3. But it also looks like WITH has a higher precedence than OR, so I'll try removing the parens.

[sunfishcode]

That worked! 0.6.0 is up, with the new license.
