Yeah, I guess, that stuff is supposed to get DIST'd in the tarball,
and should usually not be touched there during build. Running split
builds directly from the git tree might not make much sense with
gtk-doc.

Yeah, there is a lot of stuff that would be nice to see fixed, also
many of the warnings of the generated code and the over-verbose output
during the build.
