Warning on 'mktemp' [Cygwin]

On Cygwin I find this warning:

/tmp/emacs/lib-src/movemail.c: In function ‘main’:
/tmp/emacs/lib-src/movemail.c:305: warning: call to ‘mktemp’ declared with attribute warning: the use of `mktemp' is dangerous; use `mkstemp' instead

Note that 'configure' says: "checking for mkstemp... yes", so I have applied this patch:

$ cat movemail.c.patch

       *p = 0;
       strcpy (p, "EXXXXXX");
-      mktemp (tempname);
+      mkstemp (tempname);
       unlink (tempname);

       while (1)

and the warning disappeared. But is it safe apply it, at least locally on Cygwin?
