Hi all.
I'm trying to find a way to detect duplicate items in a list without
escaping to a shell.
Consider the following:
list := A B C A D C
In the list above A and C is duplicated.
I would like to find a way so I can find which items are duplicated and print
them out.
The solution should preferably work with gmake 3.81 and even better in make 3.80
Thanks in advance,
Sam
