We do have local patches against make.c and make1.c, but nothing which
should affect dependencies.  Our patches to those files make minor
alterations to messages which jam prints, add an option "critical"
modifier to actions, and alter some stuff to do with command line length
limits (as we've totally exorcised the use of cmd from our jam).

Yes, I thought that would be the case :-(.  I'll keep digging.....
