This untested but trivial patch fixes synaptic to be able to parse both
output formats by stripping the architecture suffix:
--- a/common/raptoptions.cc
+++ b/common/raptoptions.cc
@@ -222,8 +222,8 @@ void RAPTOptions::rereadOrphaned()
return;
}
while (fgets(buf, 254, fp) != NULL) {
- //mvo: FIXME this sucks (remove newline at end)
- buf[strlen(buf) - 1] = 0;
+ // remove newline at end and strip architecture suffix
+ buf[strcspn(buf, "\n:")] = '\0';
//cout << "buf: " << buf << endl;
setPackageOrphaned(buf, true);
}

All additional options intended to be used by deborphan's frontends are
documented in /usr/share/doc/deborphan/README.frontends on an up to date
Debian sid.

Trying to prevent the need to discuss details afterwards might have lead
to a bit too verbose description.
In a nutshell:
* create a set of possibly orphaned packages you want to check
* create a set of all dependencies of all installed packages
* remove packages that are in the second set from the first
* do something sane with Provides:, depending on your data structure
(Squeeze has 180 packages in main/{old,}libs with a Provides: field
and 2695 packages without.)
> * Get a set D of all Depends: and all Recommends: ...
deborphan by default also considers Suggests: as dependency.
Enhances: might be worth considering too.
