Well, as written 12 minutes before your email as reply to an email by JH Lu:

I applied not mentioned patch as Rev. 140239 and I hope that I have not
forgotten anything else. At leas the *inc and *.h files in
x86-64-linux/libgfortran/ now look OK.

Still, I wonder why that didn't fail before. There was a period when
-Wunused-variable worked. Why didn't that trigger the bug before? After
all, it is a regression?

In any case, it shows that also for doing a simple patch one should
better bootstrap (or at least rm -rf libgfortran/ in the build directory
+ build) and not only build and regression test gfortran + gomp.
