Done.

Done.

No reason. I've made this change in the new version.

And this change is made as well.

I made this change, and also changed the name of SRC to SRC_LIST.
Thanks for the review. I've posted an updated version of this patch
here: https://sourceware.org/ml/gdb-patches/2014-10/msg00870.html.
It's part of a new version of the whole patch series, updated to work
with more recent changes.
Thanks,
