We don't have any rules that actually handles archive members in the
default setup.
The rule you quote would only work for creating an archive based on a
single c file.
There is nothing in the posix description that says anything about default
rules to recreate archives.
Your "posix system" is using an extended set of rules to create libraries.
(note that the rule above is fairly useless obviously, but it's what's
mandated by posix...)
