Hm, I'm not sure what it was compiled with. I used latest tinerbox build of seamonkey 1.8pre. It might be VC++ 6... gotta give it a try.
Here is a 7zip'd version of the directory that I use to build the installer from, as well as the copy script (uses cygwin).
I've not had experience with pocket before, but I think it should work like how you explained?
