thanks for insisting on this variant.

In my first attack at this problem, I overlooked one place in
libgfortran.h, which I now was able to find and adjust.
Now everything falls into place.

As the majority agrees on this, I accept it.  The attached patch
now does this and fixes the testcases accordingly.

Done.

I also fixed a few issues in the documentation in gfortran.texi .

As I currently cannot build a full compiler (see PR112643),
patch V3 is not properly regtested yet, but appears to give
results as discussed.

Comments?
