Sorry, but I don't see your point. I know when to check for errno.
If you took the little illustrating program for a real life example of
the use of errno, that's unfortunate :-)

The problem is that the emulated/wrapped close from libc_r does not
behave like the real one. libc_r is leaking some of its guts
(the tricks it's doing with O_NONBLOCK, etc) in the interface.
This is technically a bug. The fix was trivial.
