I am not quiet sure if the GM really is the retail. I found this procedure:
1. Insert DVD / mount disk image
2. Open the folder called "instructions" (name depends on your language settings)
3. right click or control-click on the item called "Installation Instructions" and pick the option "Show package contents"
4. Open the /Contents/resources/French.lproj folder
5. Open the pdf document entitled "Instructions dinstallation.pdf"
What does this document describe? 10.6 or 10.5? snowleopard_10a432_userdvd.dmg still describes 10.5. Somehow I don't believe that Apple made this release the retail version without correcting this (and maybe more) "bugs".
I did a recursive diff on the ADC 10A432 and the Mac Box Set retail disk:
Code:
$ diff -r /Volumes/Mac\ OS\ X\ Install\ DVD /Volumes/Mac\ OS\ X\ Install\ DVD\ 2
Binary files /Volumes/Mac OS X Install DVD/.DS_Store and /Volumes/Mac OS X Install DVD 2/.DS_Store differ
Only in /Volumes/Mac OS X Install DVD 2: .Trashes
diff: /Volumes/Mac OS X Install DVD/.file: Permission denied
diff: /Volumes/Mac OS X Install DVD 2/.file: Permission denied
Binary files /Volumes/Mac OS X Install DVD/Instructions.localized/Installation Instructions.app/Contents/Resources/French.lproj/Instructions dinstallation.pdf and /Volumes/Mac OS X Install DVD 2/Instructions.localized/Installation Instructions.app/Contents/Resources/French.lproj/Instructions dinstallation.pdf differ
diff: /Volumes/Mac OS X Install DVD/usr/bin/tar: No such file or directory
diff: /Volumes/Mac OS X Install DVD 2/usr/bin/tar: No such file or directory
diff: /Volumes/Mac OS X Install DVD/usr/lib/libpython.dylib: No such file or directory
diff: /Volumes/Mac OS X Install DVD 2/usr/lib/libpython.dylib: No such file or directory

diff: /Volumes/Mac OS X Install DVD/usr/lib/libpython2.6.dylib: No such file or directory
diff: /Volumes/Mac OS X Install DVD 2/usr/lib/libpython2.6.dylib: No such file or directory
diff: /Volumes/Mac OS X Install DVD/usr/lib/libruby.1.dylib: No such file or directory
diff: /Volumes/Mac OS X Install DVD 2/usr/lib/libruby.1.dylib: No such file or directory
diff: /Volumes/Mac OS X Install DVD/usr/lib/libruby.dylib: No such file or directory
diff: /Volumes/Mac OS X Install DVD 2/usr/lib/libruby.dylib: No such file or directory
What the Terminal result shows is that the only significant difference is in the PDF for the French-language instructions.
On the ADC disk "Instructions dinstallation.pdf" are instructions for 10.5 (13 pages). The file weighs 1 MB and is dated November 19, 2008.
In contrast, the same file on the Mac Box Set correctly gives instructions for 10.6 (8 pages). The file weighs 98 KB and is dated July 21, 2009.
