 Oops, we also need BIOC[GS]ORTIMEOUT when COMPAT_50:
 
    https://nxr.netbsd.org/xref/src/sys/net/bpf.h#132
 
 Is it OK to have #ifdef COMPAT_50 (or equivalently,
 #ifdef BIOC[GS]ORTIMEOUT) in netbsd32_ioctl.c?
 
 Anyway, I would like to decide the way before proceeding further.
 
 (1) add unused "u_long cmd" argument to all netbsd32_{to,from}_foo()
 functions in netbsd32_conv.h, and move netbsd32_{to,from}_foo() in
 netbsd32_ioctl.c to netbsd32_conv.h
 
 or
 
 (2) leave preprocessor mess as is
 
 or
 
 (3) other
 
 Paul, how do you think?
