Ok, makes sense, thanks. Now I understand what I fixed.

However the windows headers don't have a really good place or uniform way to
declare either, so I can't do a bit of grepping and isolate all clsids.

However I found a big batch (160 of them) in the comdef header, with among
them the correct value of clsid_shelllink (so I know they are really
clsids). These are already committed, and I'll try to get it in 2.2.2.

On some website sb hinted that there are even more kinds (fmtids and
cgids), do you happen to know more about those too?
