Or perhaps:

#ifdef HAVE_SRANDOMDEV
  srandomdev();
#else
  srandom(time(0));
#endif

I think this is not bad solution.  If you call this several times, you
can also do

#ifdef HAVE_SRANDOMDEV
# define SRANDOMDEV(x)  srandomdev()
#else
# define SRANDOMDEV(x)  srandom(time(0))
#endif

and then call
                SRANDOMDEV();
in your code.

The project gnulib on savannah (list address@hidden) is trying to
solve this type of problems.  But I'm not sure whether it's not an
overkill to use its infrastructure just for this single small problem.
Gnulib has replacements for many functions, but I think srandomdev is
not there (yet).

Have a nice day,
