cobalt kernel compilations fails in -current

Hi!

Since several days compilation of a -current kernel for my cobalt qube
2 fails at:

      compile  KERNEL/pci_machdep.o
      compile  KERNEL/pci_map.o
      compile  KERNEL/pci_quirks.o
      compile  KERNEL/pci_subr.o
      compile  KERNEL/pci_usrreq.o
  cc1: warnings being treated as errors
  ../../../../dev/pci/pci_usrreq.c: In function 'pcimmap':
  ../../../../dev/pci/pci_usrreq.c:148: warning: implicit declaration of function 'bus_space_mmap'
  --- pci_usrreq.o ---
  *** [pci_usrreq.o] Error code 1

Kernel's config didn't change.

Maybe someone can fix this?

Thanks, Markus.
