POSIX states that ENOTSUP==EOPNOTSUPP is permissible, so you can't do this
with a case statement.

I agree - it's not worth ignoring an error unless we have a use case in
the wild of someone that generates it where we can work around it; and the
set of errors to ignore is highly context-dependent, so a generic function
will never be useful to me.
