To confirm: yes, exactly.

Quite so, although it's my understanding Posix has invented things
from time to time.  stdlib.h comes to mind.  

Sometimes, as you say, the standard is a muddle because implementations
are a muddle.  That's why I think of it as a lightlhouse: steer by it,
not at it.  If the approach becomes treacherous, steer away.  ;-)
