Adapting changes for MSYS2?

[arnold]

Hi.

A gawk user recently called my attention to:

        https://github.com/msys2/MSYS2-packages/tree/master/gawk

I have adapted the patches for gawk's test/Makefile.am and will be
pushing shortly.

Can we get the changes for compile, config.guess, config.rpath, and
ar-lib integrated directly into GNULIB, so that I can then pull them
from upstream?

They may be small enough that you don't need paperwork.

I'm cc-ing Alexey Pawlow, the author of the changes.

Thanks!

Arnold
