mkstemp declaration fix

[Bruno Haible]

Hello,

On MacOS X 10.3, one gets this warning:

mkstemp-safer.c:34: warning: implicit declaration of function `mkstemp'

The reason is that mkstemp is declared in <unistd.h>, not <stdlib.h>, on
this platform. But for POSIX compatibility, only gnulib's <stdlib.h> should
be sufficient to declare the function. I'm applying this:

        * modules/stdlib (Depends-on): Add unistd.
        * lib/stdlib_.h: Include <unistd.h> if mkstemp is desired.
        Needed for MacOS X 10.3.
