For now we remove the header file - /usr/include/X11/extensions/vldXvMC.d because it conflicts with xorgproto. We should keep the header here as soon as the next xorgproto comes out. Same applies to xorg-libx11 and XKBgeom.h
This reverts commit 64ed675d5a. Update breaks mesa3d because of the changed pkgconfig file.
