Did we do some incompatible change recently? Not too happy with this
one.

Nothing obvious, can you add printfs to the two EINVAL returns in the
case CCDIOCSET: section?

Yech! It's more complicated than that.

After trying to just do that and getting nothing, I added:
         printf("ccd ioctl: %lu\n",cmd);

as the first line of  ccdioctl(), and the output is:

Configuring CCD devices.
ccd ioctl: 3223078416
ccdconfig: ioctl (CCDIOCSET): /dev/ccd0c: Invalid argument
/etc/rc.d/ccd exited with code 1
ccd ioctl: 2149606504

So something broken in the syscall handling, the new compiler (this is
on a VAX), or something else that I don't get yet... I should point out
that apart from ccd, I've successfully booted that same kernel (another
on another machine where I was not using ccd).

And to make it clear: It never comes to the CCDIOCSET handling where it could return EINVAL. I have not really looked much deeper into the code.
