Maybe. You don't think that a 64-bit-int platform would choose to
supply a random() function with a range of 2^63-1? The HPUX and SunOS
man pages clearly specify that random()'s result is "long", so I think
a case could also be made for LONG_MAX.
I suspect we have a good chance at getting burned no matter what we use
:-(. But RAND_MAX is definitely the wrong thing.
Is it possible to test (during configure phase) and then go from there... or does it need to be the same for all platforms?
