+// AIX-SVR4: fatal error: error in backend: -msvr4-struct-return not supported on AIX
+ 
----------------
If certain front end option is not supported on certain target, I think it makes more sense to have a standard diagnostic in the driver component, instead of "crash" in the backend. 
i.e. What if we specify this option on a Windows machine? Maybe we should pursue the same behavior.
