[SAC-HELP] sac on 64-bit SMP box

[Brian Savage]

Derek,

There was a posting for me about sac on 64 bit machines, in  
particular linux.  If follows here.

<snip>
SAC is not supported on 64 bit environments, and it will produce  
unexpected results.

I would not say it was a bug, but I would say there are things in the  
SAC code which are not portable between 32 and 64 bit systems.  These  
things need to be attended to.

You should be able to run a 32 bit binary on a 64 bit system.
<snip>

Two things in specific, the declaration of the sac header on 32 and  
64 bit machines results in different file sizes, and many function  
calls are using non-portable, 32 to 64 bit, declaration of pointers.

Cheers,
Brian
