Good.

You added these fields to ‘gobject-introspection’ itself, right? That’s
where it belongs.

This will only make a difference when building packages that depend on
gobject-introspection, and that also depend on packages having a
lib/girepository-1.0 sub-directory.
(Compare to how CPATH is handled for GCC.)

Exactly. So it’s better to push a patch that adds it right after the
patch that fixes g-ir-scanner.
Thanks,
