Thanks.  Grabbed it, but it doesn't compile 'out of the box' on BONE.
I guess Haiku has moved to more standardized header names?  In particular
BONE seems to use '<netinet/icmp.h>' and such, where Haiku (and the standard)
seems to have '<netinet/ip_icmp.h>'.  The Haiku version also uses
'getprotobyname' which is still giving me trouble.

[I'll have to dig into Haiku properly some day, but so far I haven't
got myself fired up to do so...  Sad.]

Not sure I ever have.  I checked, and the 'net' folder was there (as well as
'bone'), but removing it and recompiling made no difference.  Still get
"icmp: unknown protocol" -- which seems to be from getprotobyname("icmp")
returning null.

Looking in the headers (be/bone/netinet/in.h) I see IPPROTO_ICMP is '1',
but I'm not sure how I use that value...

Thanks.
