If your referring to the MinGW64 thing, the initial problem was you were
adding another "." before the file extension, but that was a change to
the Mercury compiler, not make_temp.  There's something else weird
happening on that system which is, I think, unrelated to temporary
files.  (I'm still looking at that latter one.)
