On p5p, silence usually means either consent or complete bewilderment. In
this case, I'd venture to say it means consent (though folks undoubtedly
reserve the right to complain later, of course:-).

Causes usually need a champion to implement them.  The mkstemp() one is
slightly involved because it involves a new Configure check.  Well, here
it is, in case anyone wants to pursue this.

For mkstemp() related things, simply add these three lines to Configure

: see if mkstemp exists
set mkstemp d_mkstemp
eval $inlibc

And these lines to config_h.SH

   This symbol, if defined, indicates that the mkstemp routine is
   available to create and open a unique temporary file.
$d_mkstemp HAS_MKSTEMP		/**/

and Configure will look for mkstemp().
