Description of problem:
While using vim 8.2 on cygwin 3.3 (x86_64) on Windows 10,
when editing an existing file with vim and saving it, the Window’s
file system archive bit is always left cleared (not modified state).
This happens, whether the archive bit was set (is modified) or
clear (not modified) initially.
The problem also occurs with 'cp' command:
$ touch file1
$ /bin/cp file1 file2
$ /bin/cp --preserve=mode file1 file3
$ lsattr file?
---a-------- file1
---a-------- file2
------------ file3
Some Cygwin functions apparently clear the archive attribute
unexpectedly, for example:
int fd = open(filename, O_CREAT|O_TRUNC|O_WRONLY, 0644);
write(fd, "Test\n", 5);
fchmod(fd, 0644); // clears archive attribute
close(fd);
Same with facl(., SETACL, ...). The variants chmod() and acl() are not
affected.

Christian
