Just a quick note in case anybody should happen to use code like

$include <stdlib.h>
...
	(double)rand()/RAND_MAX

the definition of RAND_MAX in stdlib.h is wrong:

#  define RAND_MAX 32763

whereas it should be 32767.  (This is in HP-UX 7.0; earlier releases
didn't have RAND_MAX defined at all, newer ones I don't know about.)
