It is in `man cygport` for me:

$ man cygport | grep debug
        --debug
               enable debugging messages

Try `cygport --help` for better info: we should probably use `help2man` to 
update man pages, if there are mismatches.

Try running:

$ cd /home/me/cygsrc/bash-5.2.21-1.src/bash-5.2.21-1.x86_64/origsrc/bash-5.2.21
$ patch --verbose -N -s --dry-run -p1 -i

If anything is not found locally, and what that means may vary by source, it 
will be checked for in the upstream source cache ${DISTDIR:-$HOME/Downloads}, 
and what is available locally or in the upstream source cache may not be the 
same file used in the original build!

I have no idea where your sources originated without seeing the whole 
transcript, including downloadall or equivalent, but wcurl/tar/prep works for me:

I also built a bunch of updated packages from sources last weekend with no 
issues, and got nearly identical results on our CI system, from which the 
updated packages were deployed to the mirrors.

Perhaps check no other instances of required utilities are prior to Cygwin's on 
your PATH:
