Confirmed that musl's strverscmp mismatches your expectations. Myself and others think the expected behavior is ridiculous, but it's the documented behavior and it's not very useful to provide an implementation of a nonstandard function that doesn't match the one present on systems that defined it, so this should be changed. Of course we cannot use code from gnulib, though. I'll put fixing this on the agenda and hopefully we can get it in the next release after the upcoming 1.1.5 release. Thanks for the report. Rich
