any luck.

I agree.

I went through the thread and could not find the piece of information
that lead to that opinion (maybe I am just generally bad at mailing lists).

Rich Felker (you :D) argued:

That's all I found there.

FWIW I wouldn't mind if mallinfo on musl
would just return a zeroed mallinfo struct,
because I don't even know if the function is
called at all: I just know that the code won't
compile without those symbols.

Arguably, I can do that workaround myself,
so I'll just do that for now.

Thanks again for the quick reply!
