Hm, maybe best not to touch it, but still...

What's bugging me is that 0 and O_EXCL give the same answer, and
O_TRUNC and O_TRUNC | O_EXCL give the same answer, but O_CREAT and
O_CREAT | O_EXCL give different answers, as do O_CREAT | O_TRUNC
and O_CREAT | O_TRUNC | O_EXCL. I'm also pretty suspicious of
both O_CREAT | O_EXCL and O_CREAT | O_TRUNC | O_EXCL giving the
same answer. However, I have no idea what the semantics are of
the symbols the function is mapping into, so maybe it's OK.
