That reminds me: sys$check_access() does not work with NFS/DECNET files -
unless one has extra privileges, IIRC. [The end result is that access to
such files is denied, even though C code can access them.]
Perhaps we could use sys$check_access for regular files only, and use
something else (whatever was used before sys$check_access was introduced -
in 5.5.x?)
- for everything else?

I'd agree with that, but that'd require twiddling the source a bit. (Like
that's a big deal... :) The problem is that some of the VMS library
functions are returning this result--we don't special case NL: or anything,
we just call sys$check_access. It isn't entirely simple, since you need to
alter the functions that check access via file descriptor. (No sense
returning writable for a check by name and later say we can't write to a
filehandle open on the file we just said was writable by name...)
