Compiling with --lib won't create a library on Windows

[nachoverdon]

The compiler won't create a library on Windows when using the option --lib

I'm trying to build a .dll using kitc mycode.kit --lib, but instead of creating a .dll, it is creating an invalid .exe file. This is the output of the compiler:

Code used

function hello() {
    printf("%s\n", "Hello from Kit!");
}

Environment

kitc --env
