It has to be in the same directory like the target files or rename() could
fail as I understand it. But of course it's not really the current working
directory because output filespec can include a path, relative or
absolute.
My intention for using mktemp() was to make sure that one scanimage
process does in any case rename only it's own file, even if a concurrent
scanimage process (maybe handling a different device) uses the same output
file name.

Anyway I'll remove mktemp() tomorrow.
