Platform i386:

I'm getting lots of this building a kernel from a very recent current:

   cc  -O2 -Wno-error -Wno-main -I. -I../../../../arch -I../../../.. -nostdinc -I../../../../../gnu/sys -DLKM -DDIAGNOSTIC -DMAXUSERS=32 -D_KERNEL -Di386  -c ../../../../dev/ic/ncr53c9x.c
   In file included from machine/param.h:49,
                    from ../../../../sys/param.h:143,
                    from ../../../../dev/ic/ncr53c9x.c:80:
   machine/cpu.h:164: warning: `struct trapframe' declared inside parameter list
   machine/cpu.h:164: warning: its scope is only this definition or declaration,
   machine/cpu.h:164: warning: which is probably not what you want.
   
How do I clear this up?

TIA,
Paul
