As I pointed out, the API for this function, *as specified by the

To be fair, Thor, we should note that, since those strings are not
really human-interface strings but rather a peculiar representation
members of a very small set of error conditions, localizing them is
really relevant. (Not unless you try to think of the string as an
error _message_ rather than a strangely-represented error code, which,
while I suppose is reasonably likely given the strings' contents and
the preponderance of English, is really a conceptual error akin to
thinking ENOTTY has something to do with tty lines merely because it
contains "TTY" in the name.)
If that's actually the case this goes back to the original objection
where you can't simply switch based on the return. You have to setup
if/else ladders with strcmp which to be honest is a bizarre API in
that nothing else I've run into does things that way.
It's all becoming a twisty maze of things here, none of which seem to
make sense. Especially for such a small function.
