Re: star 1.5a25 (x86_64-redhat-linux-gnu): diff reports many different uname, gname

Hello Joerg,

Thanks for taking your time to answer.

I am really upset with Red Hat supplying such an old star version, all 
the more it seems it is the only available tool to save ACLs !

We have a software support agreement with them and we just submitted the 
case. I am not very keen on compiling myself a piece of software 
especially in a production environment, because I may not catch a 
problem and end-up in an even more corrupted version !

Anyway, I may compile it on test machine and use it for a try.

Best regards
Marc.
