I don't.  Why do you think so?

I'm not a perl person.  Upset is using some kind of

  use Digest::SHA;
  [...]
  my $ctx = Digest::SHA->new(512);
  [...]
  } elsif ($f eq "$d0/sha512.sum") {

This was a drop-in replacement for Digest::MD5.  Anything else I'll
let somebody do who better knows perl.

Apart from this, the sah512.sum files are not only generated for the
Cygwin release dir, they are generated on the sourceware ftp area
system-wide.
