Thanks.

It looks like my guess about vpath was correct: the failing Make
doesn't see it.  That's quite strange, since I cannot see anything in
the code that could explain the problem.  Obviously, I'm missing
something...

But before I dig deeper into the code that processes vpath, I'd like
to be absolutely sure I'm looking in the right place.  So I'd like to
ask you to run one more test.  At the end of this message you will
find a short Makefile, that is a very small subset of the Makefile you
have in the /home/Angelo/Downloads/GFortran/gcc/.build/gcc directory
in your gfortran source tree.  Please save the file below as
/home/Angelo/Downloads/GFortran/gcc/.build/gcc/cygdos-test.mk, chdir
to /home/Angelo/Downloads/GFortran/gcc/.build/gcc, and run the
following command:

    make -p --debug=i -f cygdos-test.mk

with both the patched and unpatched Make.  If I'm right, the patched
Make should fail with the same or similar error message as you saw in
your build attempt: it should complain about "no rule to make
`cpp.texi', needed by `doc/cpp.info'"; whereas the unpatched Make
should succeed and run `makeinfo'.

Whatever the results are, please send me the two logs produced by the
above command with each of the two versions of Make.  Thanks.
