DiscDev build fail.

I noticed that though there is an updated CA Certificates there is no new build of the HD4 image.

A local build failed :-

There has been some previous work in this area.

Adding type const to line 65 of DiscDev.Disc.RiscOS.Sources.SystemRes.Configure2.PlugIns.MousSetup.c.Main works.
