Comment:

 You are most likely setting `HADDOCK_DOCS=NO` in your `mk/validate.mk`
 file (on your Windows machine only, which is why you don't see these
 errors on Linux). That should normally be ok, but see below.

 > * Some unexpected failures. Let's ignore those for now, since they are
 probably all different
 Ok. These are the only problems that are Windows only in this ticket.

 >  * Some Python traceback stuff; this must be a bug.
 It was. Should be fixed now.

 >  * Tons of warnings about `haddock-interfaces`
 This is an instance of #8981. A workaround is to use `HADDOCK_DOCS=YES`
 (the default) in mk/build.mk or mk/validate.mk`.
