Plus, you can audit old binaries to find evidence this had been done  
by recompiling gcc with 5 different C compiles on 5 systems and then  
using those to compile up the claimed sources for the binary and see  
if it matches the binary in question.  If you're a system  
distributor, you limit who can inject binaries into the build system,  
log and audit it.
