If you're assuming C89 and really mean it, then I'd say "no". It seems
to me (but I admit that my memory is none too good in this area) that
X3J11 got the SEEK_* macros from SysV, but SysV had them in <fcntl.h>,
which was not something J11 wanted to pick up, so we moved them to
<stdio.h>. POSIX says they're in both places, plus <unistd.h> to boot.
So <fcntl.h> would be appropriate to pick up a few pre-C89 systems, but
I think you'd have to conditionally define them yourself if you really
wanted to be portable to pre-C89 systems.

Given the code in getpass, they are synonymous. Unless, of course,
it's possible that stdin == stderr. Or that a newly-opened stream would
compare equal to stdin. I think the former is slightly more likely than
the latter, but I don't think either is actually valid.
