Comment(by cypherpunks):

 If manuals says truth then except Linux nothing else used RAND_MAX to
 limit values returned by random(). It seems like for Solaris RAND_MAX
 defined as 32767 (can't prove but "internet" says so), while random()
 still implemented properly like documented without explicit maximum
 values.
