You mean the source tarball? It doesn't work on Linux, it doesn't even compile — the Makefile hardcodes CC to the MinGW compiler. Almost every .c file includes windows.h.

Looking at the project's issue list, they don't support other operating systems.

That source tarball is autogenerated by github when you make a release and it in no way implies linux compatibility, it is simply a way to download the source code without git.

Is this some kind of bad joke?
