The changes you propose will cause file descriptor leakage which
is not acceptable, especially not in a library.

It's true that you can get around that by closing the file
descriptor returned by mkstemp(), but that really misses the
point of the warnings.  The linker is warning you of a race
condition.  If the tmpnam() calls are going to be replaced,
the race ought to be fixed.  There's no point in doing it just
to get rid of a link warning.

P.S.  GCC 3 no longer emits this particular warning, anyway.

P.P.S. The man page for mkstemp() on my system says "Don't use this function,
use tmpfile(3) instead.  It is better defined and more portable."
