that sounds rather likely.

fwiw, the compile on HP-UX 11.11 with a rather older compiler was otherwise 
"clean" but I do have a question about:

>>   +w1 +W 474,530,2193,2236  -c entropy.c

Were those four warnings being suppressed because there was a bug in some rev of 
the HP-UX compilers?  If so, how long should that suppression remain?  The 
paranoid in me thinks that if the compiler has been fixed, perhaps suppressing 
those warnings isn't such a good idea.  At the risk of giving myself an action 
item I'm not entirely sure how to implement :), maybe it would be good to have a 
configure test to see if the compiler generates "invalid" warnings for those 
four before suppressing them.
