Why not just implement "strerror", as per the proposed ANSI C standard,
which takes an error number as argument and returns a pointer to an
appropriate message for that error, and construct the message yourself? 
This has the advantage that if you *don't* want to just blat the error
out to the standard error, you don't have to do so....
