When the temporary file is writable, Lisp COMPILE succeeds.
Although you cannot change the temporary file location,
it is OK because the location chosen by GCL is writable.
Whether Windows decides to enforce read-only access seems to
be somewhat unpredictable, so it works OK on one system and not
on another.
