I gave it some thought and was sure there would be no such case...
But now that I tested with 'zig cc' -- it apparently tries to remove
the target file before recreating and fails with accessDenied if cannot
(or, hopefully it just checks permissions, as removing /dev/null as
root would be nasty...)
Too bad, I had some plans that this change would have helped but...
