how does -fargument-alias option works ?

[Bansidhar Deshpande]

Hi ,
I came across -fargument-alias,-fargument-noalias,-fargument-noalias-global 
options options, Can you give me idea,in which kind of situations
these options are used. Are these options are effective with C or only with 
C++.
Can you plz suggest some practical situation in which these options work 
effectively for more clarification ?
Regards
Bansidhar
