Doesn't give one a warm feeling for the average level of error checking
in Unix programs, does it?

Good. I'd say we just leave it for that then.

I don't want to, because it would compromise the error checking.
For instance, if we hack the code to accept this behavior, then
it would also accept "NaNN" as soon as SCO fixes their bug.
The regression tests exist to discover platform bugs as well as
Postgres bugs. In this case, I think having them fail on unpatched
SCO platforms is exactly what should happen.
If you want, you can send in a docs patch for FAQ_SCO to give
people a clue about it.
