Maybe. It's been in the back of my mind for a long time that the _dosmaperr() mapping may be confusing us in some of these hard-to-explain trouble reports. It'd be great if we could see the original Windows error code too. Not quite sure how to mechanize that, though. Places where we do stuff like save-and-restore errno across some other operation would break any easy solution. regards, tom lane
