Hmm, did you run across this while testing your patch?

Stop in /usr/src/usr.bin/kdump.

I don't understand why it complains, since both declarations are
identical, modulo whitespace:

% grep -r bcopywrap /usr/include/netinet
/usr/include/netinet/ip_fil.h:extern         int  bcopywrap __P((void *, void *, size_t));
/usr/include/netinet/ip_compat.h:# define    COPYIN(a,b,c)  bcopywrap((a), (b), (c))
/usr/include/netinet/ip_compat.h:# define    COPYOUT(a,b,c) bcopywrap((a), (b), (c))
/usr/include/netinet/ip_compat.h:extern      int            bcopywrap __P((void *, void *, size_t));
% make DEBUG_FLAGS="-g -save-temps"
% grep bcopywrap /usr/obj/usr/src/usr.bin/kdump/ioctl.i
extern int bcopywrap (void *, void *, size_t);
extern int bcopywrap (void *, void *, size_t);

BTW, the extern keyword is completely pointless, since it is implicit
for functions.
