This change is fine, except for one thing: it relies on tempnam(),
and that is not an ANSI C function.  (tmpnam() is ANSI, tempnam() is not.)

Hence, before committing this you should add a check for tempnam()
in configure.in & runtime/conf.h.in, and do something appropriate
if the system doesn't have tempnam().
