It is already there in elisp files lisp/files.el and lisp/startup.el
(for Emacs-20.3), look for variable `temporary-file-directory'.  But
order in which Emacs searches for tmp directory location is different
for ms-dos and windows.  The only reason I can imagine is faster
startup (TEMP is more likely to be defined in ms-dos), but it is
somewhat ridiculous.

Anyway, you can override it in _emacs file with the following

(setq temporary-file-directory
      (file-name-as-directory
       (or (getenv "TMPDIR") (getenv "TEMP") (getenv "TMP") "c:/temp")))

But IMHO it should be changed in Emacs sources.
