I can't get it to build on VoidLinux Musl. Could you make a binary release? If possible using Musl?

[xplshn]

Musl can be installed on Debian, Ubuntu, Arch and other systems. The only problem is that kew depends on bits/sigaction.h which is a part of libc6, and that cannot be installed on Musl systems.

[ravachol]

It turns out bits/sigaction.h wasn't really needed. I don't think. Please grab the latest (not the tagged release) and let me know how it went.

I fixed the error. I will make a PR, but please, test it thoroughly before, I can't do much right now as I haven't got any music in my PC downloaded, you know, (Bad third world internet, Imma leave it downloading overnight)

Hi,

thank you for this. I have fixed the other warnings.
