I was talking about the replacement functions in libbb/platform.c
and all of those are either nonstandardized, or standardized only
in 2008, which is recently enough that plenty of deployed environments
don't yet have support.

It's now used in ls -v, as of a few hours ago. The alternative would
be to just surround the -v support with HAVE_STRVERSCMP and not
provide a fallback implementation of strverscmp.
