No, I said "Autotools (or other similar programs)". All I need is GNU Make and preprocessor macros. It is a marriage made in heaven. I don't want or need a configuration program. A configuration program is another point of failure. It causes mailing list messages and bug reports for me.

I have build systems that work perfectly except when I have to jump through hoops for Musl. You are trying to set policy for me. (That's what Bruno said earlier, in not so many words). Don't do that. All I need to know is what version of Musl I am dealing with and I can configure myself. Jeff
