Thanks.  Please find a few comments below.

But before that: what exactly is the MSYS target, and how does it
differ from MinGW and Cygwin targets?

In addition, I think this warrants a NEWS entry (both for Binutils and
for GDB).

What are those ^M (CR) characters, here and elsewhere?  Looks like
some artifact of the way you produced the diffs?

Why is this needed?  Did you use some version of Autotools that
produces these differences?

General comment: some of the sources patched in this series are
maintained elsewhere: Readline is maintained by Bash, Libtool is
maintained by its own project, etc.  So I expect you will need to
submit the relevant parts to their upstream projects.
