Good point. I guess what I need to do is use open() specifying O_CREATE,
and then fdopen() that file.

Question: Is the use of O_TEMPORARY to open() portable? (my win32 docs
say it will make the file automatically deleted when the last descriptor
is closed, which I didn't know before. That would make the patch much
simpler, but might require #ifdefs?)
