I don't know if you are reproducing the same problem as the OP, since the
OP didn't exactly print what error message he was getting, but you
certainly reproduced a problem.

This is probably because you've mounted / as textmode. I don't know if it
is a bug in info or in gunzip for not opening files in binary even when
they live in a textmode directory, but if you would use a binary mount,
your problem should go away.

7z is not a cygwin program (although I have built it for cygwin, and may
consider packaging it since I already package tar).

That would be because gunzip is a symlink, and cmd.com does not know how
to run symlinks. You need a cygwin shell to exec a cygwin symlink. (Hmm,
maybe that is related to why cmd.com is reporting an error for info -w
bash, since info is apparently trying to use gunzip rather than gzip -d).
