--------------------+------------------------------------
 Currently we incorrectly return -1 when sysctl fails in
 {{{
 #elif defined(HAVE_SYSCTL) && defined(HW_PHYSMEM)
   /* On some systems (like FreeBSD I hope) you can use a size_t with
    * HW_PHYSMEM. */
   size_t memsize=0;
   size_t len = sizeof(memsize);
   int mib[2] = {CTL_HW, HW_USERMEM};
   if (sysctl(mib,2,&memsize,&len,NULL,0))
     return -1;

   return memsize;
 }}}
