Not seeing -d, --default documented or supported in the code as an option flag
under Cygwin: it is available under Debian/Ubuntu at least, and probably other
Linux; neither are the file input option flags -M, --modify-file, -X,
--remove-file, or symbolic link -L, --logical, -P, --physical, or -R,
--recursive option flags.

Cygwin equivalent based on setfacl(1) would be something like:
$ getfacl -a source_file | sed 's/.*/&\nd:&/' | setfacl -f - target_file
where you are getting and duplicating the file accesses and also creating the
DACLs.

I have had success using only setfacl -m and specifying everything I want
changed or set in that argument e.g.

	$ setfacl -m u::rwx,g::r-x,o::r-x,d:u::rwx,d:g::r-x,d:o::r-x /

probably using an admin account running with elevated permissions in this case.

For Cygwin root /, I have only:

$ lsp / | cygcheck-hrsv.sed
drwxr-xr-x+ 1 $USER Administrators 0 May 31 05:19 /
# file: /
# owner: $USER
# group: Administrators
user::rwx
group::r-x
other::r-x
default:user::rwx
default:group::r-x
default:other::r-x
