Hi Earnie,
Thanks for the reply.
From your mail I understood that the patch should be modified, where the st_ino of two files are compared and apply some other logic so as to know the file's unique existance.
I searched through the gcc source but was unable to find the code, where two files were compared for uniqueness. I also don't know what other parameters will identify the files uniquely other than the use of pair st_dev and st_ino.
It will be very helpful for me if you can point me to the source where similar logic is implemented.
