[SAC-HELP] x64 compilation problem

[Brian Savage]

Yingcal,

SAC will not compile or run properly in 64 bit mode.  You need to  
compile it
in 32 bit mode. This is why the configure script insists on putting  
the -m32 flag
as a compile time option.

Running SAC on a 64 bit system as a 32 bit binary is not harmful and  
does
not show reduced performance.

Cheers,
Brian
